The Sizzix Solo Shim ensures that crafters get the perfect cut every time. It can be used with any thin materials cut with the BIGkick, Big Shot, Big Shot Express, Big Shot Pro or Vagabond die-cutting machines. This replacement Shim is made of Mylar plastic and is gray and black in color. It measures 6 1/4" x 13", so it will work with long dies. The Solo Shim must be used with the Solo Platform and a set of Cutting Pads. It will work with all thinner Sizzix dies and Embossing Folders, including Clearlits, Embosslits, Ink-its, Sizzlits, Sizzlits Decorative Strips, Simple Impressions, Texture Fades, Texture Trades, Textured Impressions and Texturz Texture Plates. It can also be used with the Wafer-Thin Die Adapter (sold separately) for use when cutting with wafer-thin dies. For added convenience, there is a diagram printed on this Shim to ensure you get the perfect sandwich.
