Replace your old ink pads with these new 6/511 replacement pads to extend the life of your self-inking stamp. Designed to fit the Trodat Professional 5211, the replacement pads come in a pack of two allowing you to maintain your clear and precise customised impression. Created with a water base, the black ink pads contain no toxic substances including no acid, formaldehyde or heavy metals. For continuous everyday use, these replacement ink pads are self-regulating meaning they will not dry out. If black ink pads would not suit your stamp, these replacement pads also come in blue and red.
