These are AMAZING!!! They measure 7 1/2 x 10 1/2 and are 1/4" thin! I started with one and now am up to just over 100 cases. I have almost all of my clear stamps sorted and mounted in these cases and now I can see everything I have and can quickly pick out just the right stamp that I'm looking for. When you purchase these from me they will come empty, but with the paper insert already attached. All you have to do is layout your stamps and then ink all the stamps at once, close the case and you will have the stamped images of your collection.
