STAMPENDOUS-Cling Rubber Stamps. These are the same premium quality precision trimmed rubber stamps as the Stampendous wood-mounted version. A piece of cling vinyl has replaced the wood on the adhesive side of the foam allowing the image to be used with any acrylic block (sold separately). This package contains Follow Art: one cling rubber stamp on a 3-1/2x4 inch backing sheet. Made in USA.
