Add an extra layer in between your cutting plates by using the Purple Plastic Shim for the Gemini Midi. Shims are used in die-cutting to make the cutting-plate-die-paper-cutting-plate sandwich a little bit thicker. This helps to get an even more precise cut from your dies, especially if they are highly detailed or thin. Package contains one 6x9 inch Gemini Midi Shim. Imported.
