Made to easily fit the 2 1/2" wide opening of the Sizzix Sidekick Machine, Sizzix Adhesive Sheets feature double-sided adhesive for optimal placement. As a stand-alone product, Adhesive Sheets offer crafters the convenience of pre-made adhesive sheets. For your creative convenience, the backing of both sides of each sheet can be easily peeled away for instant application. When used with a Sizzix roller machine, Adhesive Sheets transform crafters' favorite die-cuts into ready-made stickers.
