Squares measure 1 inch x 1 inch with 1/4 inch spacing. (Entire die measures 3-3/4 inch x 2-1/2 inch.) Designed to work together with other dies in the Series #1 and Series #3 to create dozens of window card possibilities.
Our dies work with all "personal" die cut machines, such as Sizzix Big Shot, Vagabond, Cuttlebug, Revolution, etc. Just like with any other thin dies, you will need the thick white mat (platform) and 2 of the clear cutting mats. Depending on how loose your machine is, you may also need a metal shim mat.
