The floss holder provides a firm grip for the hand, which means it can be moved quickly and accurately into every interdental space, especially in the back of the mouth. For example, you can floss easily with one hand while making calls with the other. With the floss holder, the floss does not slip out of the flosser and stays firmly in place during use because the clamping mechanism holds the floss at the end of each prong. The floss holder greatly reduces the consumption of floss:After just a few months, the savings on flossing will pay back the price of your floss holder. The floss holder is infinitely refillable, which means less plastic waste in landfills. Each piece contains 30 meters of floss, which can be used continuously for a long time. The floss holder works with any type of floss or tape.
