Built to last

For decades.

Still holding firm — long after the rest give out.

Plastic holders flex, loosen, and crack — then they're replaced and forgotten. Machined from a single billet of solid steel, ours holds your floss taut by unique design and keeps its shape through a lifetime of daily use.

Flossing was overdue for a rethink.

Problems hiding in plain sight

The reusable alternative

A reusable answer to a disposable habit.

Billions of plastic floss picks are thrown away every year — each one used for a few seconds, then left to outlast us in a landfill or a waterway. It's a quiet, daily kind of waste: twice a day, by almost everyone, the plastic piles up.

So we built the answer as a true alternative, not a compromise. It's intentionally shaped and sized like the disposable flosser you already know. Load your own floss, keep it for life, and stop feeding the stream of single-use plastic.

The Stainless Steel

Built to serve, not to be trashed.

We built this to serve you — not to be thrown away. So we designed out everything that could make it fail: no welds to crack, no glued joints to loosen, no moving parts to wear, no plastic to fatigue. What remains is the simplest possible form — a single billet of 304 stainless steel, CNC-machined to high precision into one solid piece that won't loosen, corrode, or wear out.

The result is a quiet, lifetime servant. Its non-porous surface resists fingerprints and water spots, rinses spotless, and is dishwasher-safe — so it looks considered on the counter rather than used, for years to come.

Every use, a gain — not a loss

About 20 cm of floss a session. Nothing more.

We treasure value — so we designed to consume as little as possible. Buy the holder once, and each session takes only about 20 cm of floss, and every use becomes a small gain instead of a loss.

Why it's different

Our philosophy

Sustainability isn't a sacrifice. It's an invitation to invent something better.

We don't accept that the greener choice has to be the lesser one. Real progress isn't won by giving things up or settling for less — it's created. It comes from the harder, more rewarding work of designing a genuinely better alternative: an object so well made you'll never want to replace it.

Less waste, by way of more thought. That belief is the whole reason Synerponics exists.

Frequently Asked Questions

Is it easy to use?

Yes. There's no new flossing technique to learn — you floss exactly the way you already do. The only thing to pick up is how to wrap the floss onto the holder, and that takes seconds. We've included step-by-step schematics and a short video to walk you through it.

Does the holder work with any floss?

Yes. Load whatever floss you already like — there are no cartridges or proprietary refills. You just use your own floss, about 20 cm per session.

Does it hold the floss taut?

Yes. It's a proven design, refined and validated by thousands of users, that keeps the floss firm and taut through every pass, so it won't sag or slip the way flimsy holders do. And if you like even more tension, just wrap the floss one extra loop around the post — a quick adjustment that tightens it further. Taut floss is what actually cleans between your teeth.

How often do I need to refill?

There are no refills to buy — you simply reload your own floss. Each use takes ~20 cm, so a standard 40 m spool lasts around 200 sessions. You only ever replace the floss, never the tool.

Is it safe to put in my mouth?

Yes. It's food-grade 304 stainless steel — non-toxic, non-porous, and safe for everyday use in your mouth. (The gold version's titanium-nitride coating is biocompatible too — the same finish used on surgical instruments.)

Is it hygienic?

Yes. It's a single, non-porous piece of steel with no seams for residue to hide in, and you use fresh floss every time. Rinse after use; it's dishwasher-safe for a deeper clean.

Will it chip or damage my teeth?

No. It's designed to be gentle: at just 12 g — around half the weight of a spoon — with smooth, rounded contact points. Even an accidental knock against your teeth won't chip or harm them.

How long will it last?

With proper care, it's built to last a lifetime. Because it's cut from a single piece of 304 stainless steel — with no moving parts to loosen or wear down — it keeps its shape and performs like new for years. The only thing you'll ever need to replace is the floss.
