A die-cut sticker is a decal cut into a custom shape using a die or mold using a machine that cuts around the design or artwork. Die-cut stickers are printed and set between two sheets, a clear protective shield and a back transfer lining.
To apply the decal, peel off clear layer and position sticker on a clean surface. Use a credit card to smooth over the sticker with back lining still on to remove bubbles and even out the appearance. Depending on which side the lining is on you'll need to apply it to either the outside or inside if applying to a window.
