Pearl Ex is now available in stamp pads! The stamp pads are water-soluble, acid free, archival, lightfast and washfast. They are designed for use on many surfaces, such as paper, fabric, shrink plastic, clay, leather, glass, wood and others.

Marie Segal has a great discussion of the PearlEx Stamp pads at her site - I recommend this to anyone using the Stamp pads.
