Dental Lace is a refillable dental floss and 99% zero waste product. A glass container with a stainless-steel cap holds floss that is 100% Mulberry silk. The refill bags are certified compostable and the boxes are 100% post-consumer paperboard. The container can be re-used, the bags composted, the boxes recycled and the floss biodegrades. The only waste is the waterproof label on the container, which stays on the reusable container. Candelilla wax is vegan. It is squeezed from the leaves of the Candelilla shrub. The new wax is not petroleum based and there is, as always, no plastic. Each box comes with 30m of floss plus a 30m refill. Boxes of refills also available!
