We realize that it is necessary to "prime" some brands of clear stamps by rubbing the surface with an eraser or other material. However, our clear stamps do NOT require any "Priming' at all. They are ready to use right out of the package. Inks do not pool on the surface of our stamps either. With that said, we DO recommend that you ink and stamp on a piece of scrap paper first. This gives you an idea of how the image stamps, how it looks, and if you are using correct amount of pressure.
