20 sheets of Premium high gloss (cast coated) card stock. This surface allows you to maintain maximum detail from your finely detailed stamps. It also allows you to easily manipulate your ink for dragging and blending techniques. This Premium C2S variation has the pre-digital formulation coating. Because of this, it offers faster drying, less smearing and more vibrant color retention. Coated two sides allows you to have a free “do-over” when you make a mistake.
