ColorBox Single Color PadsColorBox pigment inks are water based and formulated to stamp on absorbent papers. Ideal for embossing on coated or nonabsorbent papers because they are slow drying which also gives them a long shelf life. The rich and thick inks are fade resistant and do not bleed together. The raised inking surface is made of a high quality soft foam pad for optimum inking results with use on any size stamp. The inks are acid free, pH balanced and archival quality which stampers, scrapbookers, paper and keepsake artisans will love. 3" x 1.75".
