Penny Black Transparent/Clear stamps provide endless possibilities for creating greeting cards, scrapbook pages, home décor and more. To use, simply peel the desired image (or images) off the plastic index sheet and position on a clear acrylic block (not included). No need for adhesives as the image will cling on its own. Apply ink and stamp with light pressure. Clean and replace stamps to the plastic index sheet for storage. Transparent/clear stamps offer easy positioning and are available in styles ranging from elegant to cute. Transparent/clear stamps work together with Penny Blacks wood-mounted and Slapstick/Cling designs to create everything from exquisite special occasion to colorful everyday projects.
