Xstamper recommends using only Xstamper oil based refill ink to re-ink your Xstamper pre-inked rubber stamps. Their ink has been specifically formulated to flow cleanly through the micropores of the Xstamper laser-engraved rubber.
Using ink other than Xstamper Refill Inks can clog these micropores and void the Xstamper warranty. Please
follow the directions to re-ink your respective Xstamper model and mount. After re-inking, allow stamp to sit up to 24 hours to reach maximum saturation.
