Versamark Watermark Ink pad by Tsukineko contains clear watermark ink.
VersaMark allows you to perform a number of amazing techniques. Stamp your image onto text-weight paper to explore the possibilities of watermarking or stamp subtle tone-on-tone images onto coloured cardstock. Create a resist image by stamping on glossy and brayering with dye ink. VersaMark is so sticky that it will act as glue for chalks and pigment powders.
