Review on 🛠️ LotFancy 5-Inch 8-Hole Sanding Discs, 60PCS Assorted Sandpaper - 40 60 80 100 180 240 Grit, Random Orbital Sander Sandpaper with Hook and Loop System by Rusty Heredia

Although the size is clearly marked on the bottom of the disc I recommend using a marker and writing 60 or 80 etc as the vibration when sanding will erase the number but it doesn't the number you write in ink. Some people complain that they fly away, but that has only happened to me a couple of times when the disc has worn out and has yet to be replaced. A large number of disks of any size in one package at an affordable price. I didn't see them made in China until after they were delivered, otherwise I might not have bought them and tried to buy made in the USA instead.
