Add an extra layer in between your cutting plates by using the Magnetic Shim for the Gemini Junior. 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. Featuring screenprinted gridlines with common greetings card and paper sizes, you'll be able to line up your dies accurately for a precise cut every time. This shim is also magnetic, so it will keep your dies in place while they roll through the machine. This means that you can use multiple dies at once without fear of them moving about or colliding with each other. To care for your shim, please flip and rotate after each pass. If the shim does start to bow, flip over and pass through until it is flat again, then continue to flip and rotate as normal.
