All of Lizzie Anne Designs stamps are cling stamps...traditional red rubber stamps backed with static cling film. Cling stamps are traditional deep-etched red rubber stamps backed with a static cling film that makes them repositionable and ready to use with a clear mounting block. Because they lie flat, cling stamps are easier to store than traditional wood mounted stamps. Little Bits™ cling stamps are packaged in a standard sized jewel case—stack them in any typical cd case holder! You can also flip the case into a stand for your stamps as you work.
