The cotton swab meets sandpaper! 120- & 180 and 400 & 800 Grit Sandits are sandpaper on swab sticks that look just like Q-tips. Sandit tips are designed to get into places where regular sandpaper can’t reach. Each stick has two grits – one grit at either end. A total of 16 sticks in two packs: 8 sticks of 120 & 180 grit tips and 8 sticks of 400 & 800 grit tips.
