Plug Magnets are available for use with ink pans. Simply place one on the inside of the pan and one on the outside of the pan so they make contact. Set of two.
ALWAYS use plug magnets as a set. NEVER use plug magnets individually. You must place one magnet on the inside of the ink tray and the other on the outside in the same spot so they can magnetize to each other.
