Review on RMP Stamping Blanks Washer Aluminum Beading & Jewelry Making in Metal Stamping Tools by Carrie Spencer

They are great for stamping. I also have RMP 1 1/2" rectangular blanks that work great with these washers. They come with a protective sheet which I just stick on and then peel off after all the letters are stamped. It's a little tricky to get the small pieces in Getting 'o', 'e' and the like but the foil protects the washing machine from accidental stamp scratches so I won't remove it.I've had a lot of compliments from customers on how thick they are and they seem to be much more durable than the thin ones from stores like Hobby Lobby and Michaels.
