The Lily Thinlits Die from the Susan's Garden Collection by Sizzix is designed to cut a single sheet of cardstock, paper, vellum, or metallic foil. It is chemically etched for accuracy, simple to use, wafer-thin and portable for cutting on the go. Compatible with the BIGkick, Big Shot and Vagabond machines. Use heavyweight, smooth cardstock (80 lbs. or more) for best results. Because of the thinness of Thinlits, they may require up to three passes to cut. This set includes a storage envelope. Trim off the packaging front flap, keep and slip into the envelope for easy identification.
