I used the pack on a wood deck of over 100+ sq ft and 2 large desks. I still have plenty of paper left. The strips become unglued after awhile before the actually wear out. I feel like its still a good deal though for the hrs of use they endure. ## Frequently Bought Together - Boshcraft 21 Pack 3 x 21 Inch Sanding Belts, 3x21 Belt Sander Sanding Belts 40/60/80/120/180/240/400 Grits Assortment Sanding Belt for Belt Sander Knife Sharpening Woodworking Metal Polishing - WEN Benchtop Belt and Disc Sander with 4 x 36 in.
