Crafters Companion Gemini Junior Magnetic Shim. This is a thin magnetic shim that can be added to the layers that pass through your Gemini Junior die cutting machine. The magnetic plate has markings for easy positioning or your dies and the magnetism holds the dies in place - no need for tape etc. The shim should never be used on the cutting blade side of your die as the die can cut directly through the magnetic shim, always use it on the flat side of your dies.
The magnetic shim is a consumable item that will suffer wear and tear over time, use this as a replacement.
