Review on 🔲 Sanding Mouse Block: Optimal Backing Sandpaper for Effortless Finishing by Marco Huff

They are great - I put a 120" sanding pad on one of them and a 220" sanding pad on the other, and most of my needs were met. . They hold the pads very well. The shape is good, feels good in the hand. If, like me, you have a 5-inch random orbit sander, you can use just your pads and are protected from hand sanding and your electric sander.
