This colored Pre-Inked Stamp reads the words "PAID" and features impression dimensions of 7/8" x 2-3/4". The laser engraved rubber generated in our production factories tends to make this stamp strong for quite a few years of recurring use. Forms approximately 100,000 impressions before re-inking is needed. Please remember to apply Xstamper Red Refill Ink solely. See our product options below to include a bottle of ink to your order. Re-Inking Instructions: Remove handle and apply 3 to four drops of ink on the opening of the stamp. Ideas: Opting to re-ink your stamp over night may allow the ink to fully absorb onto the stamp pad.
