Each thread is processed with a "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 figure is remarkable compared to about 44% to 50% for other flosses. It is a dental floss that provides amazing cleaning effects and satisfies users. ■ Product Specifications Contents: 45m / 250m / 250m (refill) Material / Ingredients / Contents: (Thread: Polyester), Wax Country of Manufacture: Italy
