1 / 1Plastic-free dental floss in glass
Most dental floss is pure nylon — plastic, in other words, that you pull between your teeth every night. Ours comes in two threads: corn fibre or bamboo charcoal, both in a glass dispenser you refill.
Hold them up against each other
Ordinary floss is nylon in a plastic box
You pull it between your teeth every night and throw it away. Ours is plant fibre in a glass you refill.
The comparison is against a typical nylon floss in a plastic box, not against a specific brand.

Dental floss is usually pure nylon.
Nylon is plastic. You pull it between your teeth every evening and throw it out afterwards.
Plant fibre instead of nylon
Nylon is plastic. Silk floss is waxed with beeswax. Ours is neither: corn fibre or bamboo charcoal, waxed with plant wax, sliding between the teeth just as easily.
Corn fibre is the white one, bamboo charcoal the black. Both waxed with plant wax, not beeswax.
Thin and smooth enough for tight teeth. You will not feel a difference in the grip.
A metal lid with a built-in cutter. The glass stays on the shelf.

Denmark is throwing away, right now
The number rises while you look at it. The maths is under the card.
Our own estimate: 2 million Danes who use floss × 30 metres a year. Do the maths yourself. Spread across the seconds of the year.

What people ask us
Is it as effective as ordinary dental floss?
Yes. Both threads are thin and smooth, and remove food and plaque just as well as silk or nylon.
Why does it come in glass?
So you can refill the dispenser instead of throwing out a plastic case every month. The glass lasts forever — it is only the thread that needs replacing.
What is the difference between corn fibre and bamboo charcoal?
Corn fibre is the white one and our best seller — plant fibre waxed with plant wax, no animal products. Bamboo charcoal is the black one, the same thickness, with bamboo charcoal in the thread. Pick whichever you would rather have on the shelf.
What does shipping cost?
39 kr on orders under 300 kr, and free shipping from 300 kr and up. Floss on its own is under the threshold — add a tongue scraper or a jar of picks and shipping is free.
