Bristle type
Soft, almost always.
Firm bristles feel like they are doing more, but they wear enamel and push gums back over time. Soft bristles with good technique remove just as much. If your teeth or gums are sensitive, go softer still.

A toothbrush designed to last. Born from curiosity, built with purpose.
Merox, Founder of MARLOOP
Hi, I'm Merox.
I'm an engineer, and ever since I was a kid, I've been obsessed with the ocean and nature.
When you grow up with that lens, you start noticing something strange: some of the most common objects in our daily lives are just badly designed. Not in how they work, but in how they end.
One of those objects is the toothbrush.
Why was it made to be thrown away entirely, over and over again?
I don't have all the answers. But I knew I wanted to change that.
Every year, over 1 billion toothbrushes are discarded in the U.S. alone, and around 25 billion globally. A massive problem hidden inside a tiny object.
And the craziest part? The solution is simple.
I was first inspired by a toothbrush I bought in Italy in 2018. One I still use today. It wasn't perfect, but it made me question everything.
That single brush sparked an idea that wouldn't go away.
That's how MARLOOP was born.
The toothbrush from Italy, 2018. Still in use today.
The University of Chicago wrote about how MARLOOP started and where it’s headed.
Read the articleAt MARLOOP, we're here to close the loop. Rethink a small everyday habit and turn it into something better.
A toothbrush designed to last.
Designed to feel like yours.
Designed so we stop throwing away the whole thing, every time.
Welcome to MARLOOP.
MARLOOP joins mar, Spanish for sea, with loop, for the circular economy at the heart of what we do.
The mark above the wordmark is a thin swell line. To us it is a wave — something good to watch, like the daily ritual we want to build. When we showed it, people saw a tide, a mountain, the roof of a house, even a sun. We love every one of those. Like the drawing in The Little Prince that grown-ups take for a hat, it leaves room for imagination, and we want it to stay that way.
The colors come from the shore: deep water, bone, shells and wet sand.
Everything you need to know about MARLOOP.
There is no subscription yet. In the pre-sale you buy once: the 3-in-1 system at US$ 45 / ARS$ 69.000 — anodized aluminum handle, toothbrush head with soft bristles, stainless steel tongue scraper, stainless steel floss head and the basic Holder — or toothbrush only at US$ 30 / ARS$ 32.000, which is the handle and the toothbrush head. The premium Holder is +US$ 10 / +ARS$ 8.000. Every first order ships with five toothbrush heads at no cost, around a year and a half, and engraving your name on the handle is an option that is free for everyone in the pre-sale. Refill subscriptions open once our own logistics network is in place.
Argentina: December 2026. We are aiming for around the 15th, so it is in your hands before Christmas. The exact date is not fixed yet — it depends on the batch leaving the workshop — and we will email you with the real one as soon as we have it.
United States: January 2027. It is one shipment crossing a border, so it lands a few weeks after the Argentine one.
These are the dates we are working to, not promises. If anything slips we will tell you before you find out on your own.
Once refill subscriptions open, replacement heads will ship on the 21st of every season: March 21, June 21, September 21, and December 21. We consolidate all subscriber shipments into one delivery per season, which reduces our carbon footprint significantly.
Yes — at any time, no questions asked. Write to hello@marloopbrush.com and we refund you in full. There is no subscription to get out of: the pre-sale is a single purchase, so cancelling is just cancelling that order. If it has already shipped, write to us anyway and we will sort it out.
Traditional toothbrushes are designed to be thrown away entirely every 3 months. MARLOOP is different: only the small bristle head gets replaced, which is just 10% of the plastic of a regular toothbrush. The handle is made from premium materials, personalized with your name, and backed by a 10-year warranty.
It is not running yet: the take-back programme starts in 2027, together with the refill subscriptions. From then on, every refill will arrive with a prepaid return envelope for the old head, and we collect and recycle everything that comes back. If your handle ever reaches the end of its life, we will take that back too. Pre-sale orders are not part of it yet.
Not yet. A children's version is planned for 2027. The first batch is the adult handle only, in one size and one bristle type.
Every MARLOOP handle comes with a 10-year warranty. If your handle breaks, cracks, or shows defects during normal use, we'll replace it for free. We stand behind the quality of our product because we built it to last.
The engraving is permanent and done during manufacturing, so it can't be changed after your brush is made. Take your time choosing. This toothbrush is going to be with you for a very long time!
We're launching first in Argentina and the United States. Other countries will follow soon. Join the waitlist to be the first to know when we expand to your area.

Start ShoppingBuilt from the start to do less harm. Here's how we hold ourselves accountable.
The handle is anodized aluminum and the tongue scraper and floss head are stainless steel. Both can be melted down and made again, over and over, without losing anything — unlike plastic, which degrades a little every time. Only the brush head still carries plastic, which is where the 85% comes from. Our roadmap includes moving those bristles to a bio-based, nylon-free material.
Recycling well matters less than not producing the thing at all. At four brushes a year for eighty years, one person sends around 320 toothbrushes to landfill. A MARLOOP replaces all of them: you change a head roughly every three months and keep the handle. The tongue scraper and the floss head are designed never to be replaced at all, and the floss head means no plastic floss picks in the bin either.
Paper, and as little of it as we can get away with. We keep plastic to the absolute minimum we can, ship in bulk rather than one parcel at a time, and size every box to what is actually in it.
Every brush head you return will get a second life: used heads and handles go back to being material. It starts in 2027, with the refill subscriptions — the prepaid return envelope needs the return route to exist first. It is not running during the pre-sale.
See how it works →Once refill subscriptions are running — after the pre-sale, from 2027 — every replacement head ships on the 21st, timed with the seasonal equinoxes and solstices. One consolidated route per season instead of a parcel whenever somebody runs out. We are also committed to working with EV-based last-mile carriers.
The handle carries a 10-year warranty. If it breaks, cracks or the thread fails in normal use, we replace it rather than asking you to buy another one. A product that is only sustainable while nothing goes wrong is not sustainable.
We're working toward becoming a certified 1% for the Planet member — committing 1% of annual revenue to vetted environmental non-profits. Every MARLOOP sold will contribute to the planet we're protecting.
B Corp measures a company's full social and environmental impact — not just what it sells, but how it operates. We're actively working toward meeting the rigorous standards required to certify.
Transparency matters to us.
We want you to be in the MARLOOP. #BeInTheLOOP
Join the WaitlistA simple and complete routine is the pillar of great oral health.
Five moves, twice a day. That is the whole thing.
Point them towards the gum line rather than straight at the tooth. That edge where tooth meets gum is exactly where trouble starts, and it is the spot most people miss.
Short back-and-forth wiggles to loosen things up, then a sweep away from the gum. Outer surfaces first, then the inner ones. Gentle beats hard every time.
Flat back-and-forth strokes across the tops of your molars, where the grooves collect the most.
The forgotten step. A scraper lifts far more than a brush does — and it is where most bad breath actually lives.
Twice a day, between every tooth. Curve the floss around each one and slide it just below the gum line — this is the only part of the routine that reaches where bristles physically cannot.
Most people think they have brushed for two minutes when it has really been about 45 seconds. Split your mouth into four quadrants and give each one 30 seconds.
It wears down enamel and pushes gums back, and neither grows back. If your bristles splay outwards, you are pressing too hard.
Plaque is a sticky film of bacteria that builds up between teeth and just under the gum line — two places bristles simply cannot get to. That is what flossing is for, twice a day.
You produce less saliva while you sleep, so whatever is left on your teeth at bedtime sits there undisturbed for hours.
Every three months — or sooner if the bristles look bent, splayed or flattened. Worn bristles stop reaching where they are meant to, so an old brush works noticeably less well than a new one. It is also worth swapping after you have been ill.
This is why MARLOOP ships on a rhythm you choose: the head arrives about when the old one stops doing its job, and the handle stays with you.
Brushing is one third of it. MARLOOP's 3-in-1 system is built around all three, on one handle.
Two minutes, twice a day, soft bristles, 45°.
Your tongue, once a day. The step almost everyone skips.
Twice a day, for the places bristles will never reach.
General guidance, not dental advice. Your dentist knows your mouth — follow them first.
A simple and complete routine is the pillar of great oral health — and it starts with the right brush.
It comes down to these three.
Soft, almost always.
Firm bristles feel like they are doing more, but they wear enamel and push gums back over time. Soft bristles with good technique remove just as much. If your teeth or gums are sensitive, go softer still.
Smaller than you think.
A compact head turns more easily in your mouth and actually reaches the back molars, which is where brushing tends to fall apart. A big head feels efficient and quietly misses the hardest spots.
Tapered tips reach further.
Rounded tips clean the flat surfaces well. Finer, tapered tips slip further between teeth and just under the gum line — the areas a brush usually leaves behind.
Every three months — or sooner if the bristles look bent, splayed or flattened. A worn brush is measurably worse at cleaning, no matter how good your technique is. Swap it after being ill, too.
On MARLOOP you replace the head, never the handle. One handle, a fresh head on your own schedule, about 90% less plastic each time.
The brush matters less than how you use it. Two gentle minutes with a soft, small-headed brush beats thirty rushed seconds with anything.
Bristles bending outwards are the clearest signal you have — both that the head is done, and that you may be brushing too hard.
A simple and complete routine is the pillar of great oral health. Both work. With decent technique, a manual brush cleans your teeth perfectly well, and the research is not clear about the gap most people assume is there. It is far less of a decision than it is made out to be.
Where an electric brush genuinely helps:
Where manual holds its own: nothing to charge, nothing to break, no batteries to eventually throw away, and total control over pressure. It also travels without a thought.
MARLOOP is manual by design. A brush that lasts ten years is hard to build around a motor and a battery — and once the handle is permanent, the only thing you ever replace is the head.
General guidance, not dental advice. Your dentist knows your mouth — follow them first.
Every MARLOOP product is designed to come back. Here's how we close the loop.
Coming 2027 The take-back programme starts with the refill subscriptions, once our own return route is in place. It is not running during the pre-sale — what follows is how it will work.
Closing the loop
Uses post-consumer recycled (PCR) materials as input.
Durable design, ergonomic handle, long-lasting use. Your MARLOOP product.
Only change the brush head, reducing waste by 90%.
A take-back scheme for returning used heads and old handles for processing.
Enjoy your personalized, durable toothbrush. The handle is built to last years, not months.
From 2027, a fresh replacement head arrives on the cadence you pick. Pop off the old one, click on the new one.
From 2027, every refill will arrive with a prepaid return envelope. You use it to send the old head back.
Used heads and old handles are processed and turned back into recycled materials. The loop closes.
Every MARLOOP toothbrush you use is one less in a landfill.

El cabezal de cepillo es un consumible: se recomienda cambiarlo cada 3 meses aproximadamente. El raspador lingual y el cabezal para hilo son de acero inoxidable y no están pensados para reemplazo periódico.
Las suscripciones de recarga todavía no están disponibles. Lo que el sitio muestra sobre periodicidad y planes es una vista previa de cómo va a funcionar y no constituye una oferta. La preventa incluye 5 cabezales sin cargo y nada más.
El programa de devolución de cabezales usados arranca después de la preventa, cuando esté armada la ruta de retorno. La devolución va a ser voluntaria y gratuita, y no es condición de la garantía. Los materiales devueltos pasan a ser propiedad de MARLOOP y se procesan para reciclaje.
Las cifras de impacto publicadas en el sitio son ilustrativas, calculadas sobre supuestos declarados, y se actualizan cuando se cierre la lista final de materiales.
El grabado es permanente y se hace durante la fabricación, así que no se puede cambiar una vez iniciada. Nos reservamos el derecho de rechazar, antes de fabricar y con devolución total, textos ofensivos, discriminatorios, que infrinjan derechos de terceros o que suplanten a una persona.
Sumarte a la lista de espera no reserva ni garantiza una unidad del lote, ni fija un precio: solo te avisamos antes que al resto. Podés darte de baja cuando quieras. El número de posición que muestra el sitio es orientativo.
