Alpha Bits™ cling stamps are big alphabet sets designed especially for scrapbookers! Stamps are made of traditional, deep-etched rubber backed with a static cling film. Alpha Bits need to be trimmed. Rubber strips have been pre-cut, making it easy to trim out each individual letter. Trim closely around each letter with a pair of scissors. A plastic storage sheet is included for you to store your stamps on once they have been trimmed out. Stamps are to be used with a clear mounting block. Ethan Letters are 1.5" Tall
