This Top Plate Extender is part of the FOILPRESS Collection from Gemini By Crafter's Companion. This top plate extender is required to use the FOILPRESS machine (sold separately) in the original Gemini. "This plate extends the width of the FOILPRESS so that the sensors on the original Gemini will be activated when it is passed through", per the manufacturer. This plate measures 10.2" x 7.9". With this extender, the FOILPRESS machine, and your Gemini machine, you will be creating beautifully foiled projects in no time!
