Sizzix Movers & Shapers are creativity in motion! With these movable magnetic dies, now you can create a card or envelope with a window anywhere you want for a truly customised shape-cutting experience. This Movers & Shapers window die showcases the bold and edgy style of Tim Holtz. The window die must be used in any one of the Movers & Shapers base dies or base trays. Creative Note: All Movers & Shapers Base Dies are designed to work with Movers & Shapers Magnetic Dies to cut a window within a shape. However, when Movers & Shapers Base Dies are used without Magnetic Dies, special Magnetic Ejection Foam is needed to eject the die-cut shape. One piece of Magnetic Ejection Foam works on all Movers & Shapers Dies, no matter the design.
