Use rectangular stamp for addresses and other everyday uses. Photopolymer dye delivers sharp, fast impressions. Alignment marks and see-through base help you put your message right where you want it. Ridges on the side of the mount offer a no-slip grip. Self-inking stamp does not require a separate ink pad because it re-inks after each impression, making it perfect for fast, repetitive use. Classix Custom Stamp features a rugged plastic body for durability. Rubber feet keep the stamp stable and decrease slippage. Ink is available in red, black, blue, green or purple ink. Contact customer service to customize self-inking stamp.
