CLEARSNAP-ColorBox Pigment Inks. These water based inks were formulated to stamp on absorbent papers. But because they are slow drying they may be used for embossing techniques on coated and non-absorbent papers. They also have a longer shelf life. The rich thick inks are fade resistant and do not bleed. The raised inking surface is made of quality soft foam for optimum inking results. These inks are acid free; pH balanced and archival quality. Each pad measures 2-1/2x4x3/4in. Made in USA.
