Sanding sticks (10-1/2″ overall length) with molded plastic handles come in two widths– 1/2″ and 1″. Both are packed with an 11″ long, 120 grit cloth back sandpaper strip.
Replacement strips are available in packs of 10 per grit or assortment packs with 2 of each grit.
3M Micron Graded Wet/Dry Polishing Papers cut into strips from 8-1/2″ x 11″ sheets work well (for fine polishing on smooth surfaces).
Emery paper cut from 11″ sheets or 1″ or 2″ wide rolls can also be used with the sticks.
