Dental floss exclusively for dental clinics, with 384 fibers that remove debris from between teeth. When it absorbs saliva, the 384 ultra-fine floss fibers, bundled like a single thread, expand softly, removing plaque from every corner in one go. It gently touches the gums, so there's no worry of causing injury. ■ Floss recommended by a leading expert in floss research Floor Floss has been tested by a professor at the University of Genoa, Italy. This is a highly reliable product recommended for its contribution to gum health. ■ Made in Milan, Italy Milan, Italy, is a city of textiles and fashion. In Italy, the use of dental floss is commonplace, and children use it from a young age. Because this product uses materials from Italy, where dental floss is as common as breathing, it is high-quality and very durable. You can use it with peace of mind, as there is little chance of the floss breaking during use. ■ Fine fibers & Afro processing The softness of the fibers is a key feature. It can thoroughly remove debris between teeth and plaque near the roots (the base where the teeth meet the gums) without damaging the gums. The thread that looks like one is actually an aggregate of 384 fine fibers (expand type). Each fiber has an "Afro processing" that curls and undulates, firmly removing bacteria lurking in the gums. ■ Amazing plaque adhesion reduction rate The average plaque adhesion reduction rate for the Floor Floss user group is about 70%. This is a remarkable figure compared to about 44% to 50% for other flosses. This dental floss provides users with satisfaction through its amazing cleaning effect. ■ Product Specifications Contents: 45m / 250m / 250m (refill) Material / Ingredients / Contents: (Thread: Polyester), Wax Country of Manufacture: Italy
