Tim Holtz has designed these fabulous embellishments! Time tells a story and each day unfolds a new chapter. Whatever your way of capturing everyday, these sprocket gears can add a little mechanical element to your projects. Fasten them with brads, wire, or other hardware to add an industrial feel to your work. The Sprocket Gears vary in size (see picture on this listing for more detail). The package includes 12 gears (4 of each antique finish - nickel, brass, and copper), which measure from approximately 0.75 inch to 1 inch.
