A clear rubber stamp is a stamp made from polymer as opposed to rubber. Polymer stamps cling to an acrylic block and are repositionable. Because the acrylic block is clear, it is easy to see where to position your stamp. And you only need a few blocks of various sizes since you can take one stamp off and place another one onto the block. Also, most clear stamps are not mounted so they are easy to store. Scribbling Club stamps are made from clear or clear red polymer. Scribbling Club stamps can easily be customized and personalized and make great gifts.
