The Inkadinkado Embossing Pen uses ink that is untinted and slow-drying for the purpose of achieving the dimensional effect of embossing. The pen's fine tip allows you to apply ink to selected or detailed areas, and the dabber tip works for larger areas. Apply your color choice of embossing powder to the stamped image, shake off the excess, then heat set. Ink is water-based, acid-free and nontoxic.
