A review for Die cut stickers by Dave Taylor.
They're really solid stickers. Gave out 500 to kids during the 4th of July parade, and they all went bonkers for them, but if I had a complaint, it would be mostly about the difficulty in peeling off the backs. Maybe it's the relative thinness of the sticker? Or the backing? Or both? Or not having any backing margin around them? Whatever it is, it's a real challenge to peel them, and kids usually have to get help from parents. I can barely peel them myself without a steady hand and reading glasses.
