VERSAMARK-Watermark Inkpad 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 a "glue" for chalks and pigment powders.
