This is a 4 in. x 5 in. acrylic block with a handle. So easy to hold and use! The bottom of the mount is slightly curved so that even the largest stamp only contacts the paper one section at a time, requiring less pressure and resulting in clean, even impressions. It is made to make stamping large stamps easier (works with the Cover-a-Card cling background stamps): use it with all of your unmounted rubber and clear stamps. Use any raised ink pad with it by holding the mount in one hand with the rubber facing up and tapping the ink pad to cover the surface of the stamp.
