This unit consists of a Porelon ® pad and cardholder mounted on a 6" x 24" board with rubber feet. The pad provides prints equal to those produced with a roller and slab. Place the unit on a counter or high table so the working height is approximately 42" from the floor. When finished, the unit is easily stored in a closet or cabinet. The cardholder is normally mounted on the left. If preferred on the right, please note on your order.
