Pre-inked stamps are made of a porous stamp die and the ink is infused into the stamp die. These professional stamps do not require a stamp pad and are compact and have fewer moving parts than the self inking stamp. The pre-inked stamp will last for thousands of impressions and can be re-inked if needed.

The ink colors available are black, red, blue, green and violet. The stamps are not suited for use on non porous surfaces.
