“Our stamps come mounted on Cling Cushion Foam. We recommended that you trim around your image, leaving about a 1/4″ of extra rubber around the whole image or sentiment. Our stamps are deeply etched to ensure your images remain sharp. Once trimmed, our stamps are ready to be used with an acrylic block. Here is a video link for a demonstration on trimming our stamps:
Package includes 1 4 x 6 inch rubber sheet with 10 sentiments which range from approximately 1 3/4 x 1/4 inches to 2 1/2 x 1 1/8 inches.
