The ColorBox full size inkpad is filled with loads of juicy color that lasts and lasts. Think mayonnaise. Mayonnaise and pigment ink are about the same consistency. Thick and rich, pigment ink sits on top of the paper. Pigment inks are generally pretty slow drying, giving you plenty of time to emboss and blend. These inks offer long lasting, luscious color from delicate pastels to deep, saturated hues. ColorBox Pigment ink is light-fast and acid free. The raised pad allows the inking of any size stamp. Large size, raised pad and long lasting color mean great value.
