This is a 2 piece die set that will cut and score an A2 size top fold card base. It includes one plain layer. Card base finished size when folded is 4.25" x 5.5". Plain layer finished size 4" x 5.25". This will work in a standard die-cutting machine such as a big shot but you will need extended plates. This die will make it so much easier and faster for you to make your card bases!
