Measuring 6" x 6", Bold Prints background cling stamps are large enough to fully cover an A2 card, and can be rotated for use in any direction. Handmade in the USA, they cling to an acrylic block, clean with water or stamp cleaner, and store easily when not in use. Artist tip: Use without a block! Place rubber face up, apply ink to the design, and then press your paper to the inked rubber.
