The price was right so I grabbed these. I like them. they are about 3/4 inch wide, 1 3/8 long and about 3/8 inch thick. A fairly hard foam back. When I do color or clear sanding I only do about a square inch at a time and these are the perfect size for me. So far I've only used the 2000 grit on clear. When I've cleared again I was very happy with the results. They are called Godhandtool (I'm sure something is lost in the translation!). You get 5 grits and you get two blocks of each grit.
