The AP 3

With the AP 3 you can quickly and accurately make "hang holes" or rounded corners on individual skin and blister packaging cards, as well as header and insert cards. The AP 3 uses a wide variety of inexpensive, high quality steel-rule dies. (One standard "HANNAN® slot" die is included.) If desired, it can  also be used for punching foam, leather, plastics, fabrics, and a wide variety of other materials.
