8" Soft Sanders Wet Dry Hand Sanding Block Kit 10-Pack. I actually use these. They are more flexible than a dura block. They have some definite plusses. The only negative I really have is if you leave some brands of the sticky back sandpaper on it over an extended time period, when you then go to pull it off, it can pull a little of the foam off with it. And this is for 10 of the 8" blue.
