We're so excited about this set of edger dies. Here's how they work: The bracket edge die cuts a normal edge. Then, pick your favorite insert and place it within the bracket. With 1 set of dies, you can get 4 different looks! But that's not all, you can also use the inserts alone without the bracket edger for even more looks. They will each cut in a "reverse" style, meaning that they leave the open design in your card front. There is so much you can do with this set of dies!!! The dies are all 5.5" long. Our Frantic Stamper Precision Dies work in most consumer table top die cutting machines such as the Cuttlebug, Big Shot, Vagabond, Boss Cut, and Grand Calibur. Some dies may require the use of a metal shim depending on your machine. Designed by Kathy Berger for Frantic Stamper Inc. (c) 2017 Frantic Stamper
