Spellbinders-Wizard Nestabilities Dies. These dies will work in most any die-cut machine you may already own. If you do not already have a machine, Spellbinders has their own, The Wizard Universal Embossing and Die-Cutting System (sold separately). Each set of dies comes with large and small or standard and petite, and scalloped and straight dies in sizes from 1/4in. to as large as 5- 1/2in. They nest within each other and each die in any given set increases in size approximately 1/4in. from smallest to largest. Each set contains four individual sets. Fantastic for cutting, embossing, and stenciling paper, cardstock, craft foam, leather, vellum, chipboard, foil and much more!
