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) . Simply remove the disposable acetate layer revealing the vinyl cling with printed image, press onto a block, align and stamp! Use any ink that can be used with traditional wood-mounted stamps and clean with wood-mounted stamp cleaner. This package contains Raven Background: one cling rubber stamp on a 6x4 inch backing sheet. Made in USA.
