Perma pre-inked stamps are the original pre-inked stamps. The micro porous material contains sufficient ink to give many thousands of impressions. Simply remove the protective dust cover and the stamp is ready to print. When the impression begins to fade, it can be refreshed with the perma re-inking fluid. We also recommend that your perma stamp is periodically refreshed to prevent it drying out and causing contraction of the die and potential damage.
