This set of three Looking Glass dies is from Hero Arts. These thin metal dies are designed to create windows, backgrounds, and to build layered scenes. There are three dies in this set to build with. There is one with a banner in the corner across the top, one with the banners, balloons, and a cake, and one with banners, a balloon, and a present. These dies are compatible with leading die cutting machines. These dies measure 2.06" x 2.06". These scenes can be added to cards, scrapbook pages, tags, journals, planners, and other paper crafting and mixed media projects.
