Keeping track of all those little details just got a whole lot more fun when you use the Calendar Thinlits Die from the Sizzix Life Made Simple Collection. Highlight all those special dates on your papercrafting projects to give them that extra added layer. These wafer-thin chemical-etched die sets are designed to cut a single sheet of cardstock, paper, metallic foil or vellum. They are compatible with the BIGkick, Big Shot, Vagabond, and Big Shot Pro machines and require the use of a pair of cutting pads as well as the machine's multi-purpose platform. This package includes nine dies that measure approximately 5 7/8" x 4" to 3/4" x 3/4".
