VersaMark is a great colorless ink that acts as a glue for chalks and used to stamp subtle toned images onto colored cardstock; you can sprinkle glitter over it, use it to soften colors, etc. It is a non-toxic ink that can be used for watermarking and creates translucent images. Nice on tissue paper or any colored paper (will result in one shade darker image). VersaMark is a translucent substance, that color is added to create ink, and is sticky like glue. Can be stamped on paper and dusted with chalk. Can be used for Heat Embossing or Emboss Resist.
