This two piece thin metal die set, Mini Envelopes, is from Paper Rose. This die set cuts out an envelope with rounded flaps or a standard envelope. These dies are compatible with leading die cutting machines (sold separately). Due to the intricate nature of the dies, a metal shim (sold separately) may be required in some machines. These envelopes can be used on cards, scrapbook pages, tags, journals, planners, and other paper crafting and mixed media projects. The closed envelope measures 1.06" x 0.787".
