We recommend you remove the ink cartridge that holds the pad and replace the plastic snap on cover after each use. Store the stamp and cartridges in the zip bag the stamp arrived in.If the pad does need more ink… don’t overdo it. Whether black or white ink… just a few drops in the center of the pad should do it.If you decide to keep the pad/cartridge in the stamp... be sure to partially depress the stamp which lifts the name imprint off the ink pad, and slide the tab button on the stamp to lock it in that position.
