FINISHLINE GRUNGE BRUSH 齒片清潔毛刷

Gear Floss is made of microfiber rope, which works by attracting, removing, and holding grime. Other materials simply move grime around. Microfiber works by capturing dirt, grease and particles inside its star-shaped grooves. Dirt is held deep inside the core of the fiber. Microfibers remove grime better than any other material known to man! Gear Floss is highly tear-resistant and is washable.
