Review on Sackorange 5 inch Hook and Loop Hand Sanding Block - Sanding Pad - Hook Backing Plate for Sanders/Polishers by Douglas Irwin

I try to sand smooth, fairly small objects (1 square foot) although I don't think it will change my mind. The Velcro holds the sandpaper very well. Much better in my experience than a 'regular' sanding block where you fold the sandpaper around the edge and secure it with some sort of pin. Pleasant in the hand. The sanding block material itself has just the right amount for my projects. I'm glad I came across this project. Now I bought a few and just attach different sandpapers of different grit to different blocks and use them as I please. So I have a 220 block that I marked and just use for sanding with 220 grit sandpaper.
