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.
