Reusable Floss Holder
Reusable Floss Holder
Floss like you mean it — for life.
The world doesn't need another plastic flosser. It needs one that lasts. Our floss holder is machined from a single piece of solid stainless steel — no joints, no weak points, no compromise. It works with any standard dental floss, giving you the leverage and control of a traditional flosser without the plastic waste. Load it once, floss, rinse, repeat: no cartridges, no refills, no landfill.
Switching to a reusable flosser is one of the smallest changes you can make with one of the longest payoffs — fewer single-use plastics in your bathroom, and a zero-waste routine that never asks you to sacrifice performance for principle. Solid stainless steel. Minimal waste. Built to last a lifetime.

Truly built to last
A single piece of steel with no moving parts — nothing to loosen, wear, or fail. Engineered to perform reliably through years of daily use.
CNC-machined precision
Each holder is CNC-machined from solid stainless steel to tight tolerances, holding floss firmly taut throughout every session with no degradation in performance over time. The design has been refined and validated by thousands of users in the maker community.
304 stainless steel
Manufactured from 304 stainless steel with a polished, non-porous surface that is simple to clean and keep sterile — safe and hygienic for everyday use.
A familiar, practical format
Sized to match a conventional disposable flosser, the holder requires no change in technique — a straightforward alternative that fits seamlessly into your existing routine.
Lightweight and portable
At just 12 g with an integrated keychain loop, it travels easily in a pocket, bag, or on a keyring — ready whenever you need it.
A sustainable choice
A refined, reusable alternative to single-use plastic that reduces everyday waste without compromising on quality or convenience. Each session uses only ~20 cm of floss, so a standard 40 m spool provides approximately 200 uses, with no proprietary refills required.

Materials and care
Materials and care
Material
Made from food-grade 304 stainless steel — no plastic, no microplastics, and no BPA. Independently tested by TÜV Rheinland for metal migration under food-contact conditions, nickel release, and lead and cadmium content. No substance was detected above the laboratory's reporting limits in any test. Stainless steel also resists bacteria buildup far better than plastic, so it stays hygienic with basic care.
Care
Rinse the holder with warm water after each use. For a deeper clean, wash with soap and water or run it through the dishwasher. Dry thoroughly before storing to prevent water spots. With proper care, the holder is built to last for years — you'll only ever need to replace the floss, not the tool.

My gosh, this thing has revolutionized my flossing habits. NO LONGER will I have to purchase disposable flossers, I have a sleek designed, high quality, stainless steel reusable flosser. This thing is fantastic and just really pretty.
The price is a bit steep but that is only because of the market and demand etc. it is a great product
Really good quality and exactly as described. Easy to use, particularly with my TMJ. Arrived very quickly.
Love the engraving option. It made it really fun
Best solution for zero plastic waste when you do not have a flexible mouth to use straight from the spool. I may just need to improve my flossing technique, but this is a phenomenal product for a simple life.
It is as it says on the tin - very sturdy, easy to use, and small enough you don't have to unhinge your jaw when you floss. Will be using this for many years to come.
Wirklich raktisch, funktioniert gut, empfehlenswert
An innovative design, well executed
objet de bonne qualité
Item is built very well no moving parts which I love, same millions of floss picks from the land fills. My only gripe is it's hard to get the floss to stay on tight. Once you have done it a couple times it gets easier. Also metal in your mouth is questionable I feel this is a chipped tooth waiting to happen. I love the idea, I'm not in love with this version of it.
This flosser is a fantastic replacement for a plastic flossers. However there are 2 things to keep in mind. A plastic floss may stretch and become loose and slick flosses may need many wraps to reduce slippage and loosening.
Once you get a good used to the setup you need everything works good, it's easy to setup, clean, and use and I expect it to last basically forever.
Great way to reduce plastic waste! I was hesitant because I thought the metal might be harder to use but it’s worked great. It takes a few times to figure out how to wrap the floss but they give good directions!
I love the concept but we have yet to be able to floss all our teeth with it. It seems impossible to keep the tension.
This is for my mom’s birthday, I hope she likes it!! It is just so practical (she’s like that) btw it can on time, it vary thin so it fits in anything and the metal is very strong 💪
Exactly what I was looking for and wanted. Such great quality and the size doesn’t mess with my TMJ.
Great item to replace all those disposable ones.
