This replacement pad is compatible with the Shiny S-Q12 self-inking stamp. This pad uses water-based ink which is best when stamping on documents, flyers, non-corrugated cardboard, envelopes and other office materials. Add some color with your choice of 11 different ink color options. It can even be re-inked with water-based ink for continued use. Not recommended for glossy and non-porous surfaces.
