To help achieve an even more precise cut from your dies, especially if they are highly detailed or thin, an extra layer in your die-cutting 'sandwich' is sometimes required. This is exactly what these plastic shims are designed for. Shims make the sandwich that little bit thicker, so, depending on what you're trying to cut or emboss, you may need this extra depth to give you a helping hand for that perfect die-cut or embossed result.Details:Purple6" x 9" each2 shimsPlasticFor use with Gemini Midi die-cutting and embossing machine (sold separately)
