Our 1 Line long and narrow Custom Self Inking Rubber Stamp with an ink cartridge in the stamp. The rubber stamp takes ink with a mechanical action each time the stamp is depressed for a neat and clean rubber stamp impression. Over 1000s of impressions before requiring refill. The ink pad can be refilled with self inking rubber stamp refill ink, or the ink cartridge can be replaced with a new replacement ink pad. Works best with normal paper. Not suitable for use on glossy and wax paper.
