Photopolymer is latex-free. These stamps, if stored properly, should last a lifetime and privde clear, crisp images time and time again. Photopolymer stamps should be used with clear acrylic blocks to make placement and clean-up quick and easy. Should your stamp lose stickiness, wash it with warm soap and water or clear stamp cleaner.
