Scratch-off Sticker Sheets have an adhesive film with an opaque coating. Simply print the text that you want to be temporarily hidden onto a a regular piece of paper (or other material) and then adhere a cut-out shape from the Scratch-off Sticker Sheet over the printed area. The printed text will remain covered until you scratch off the opaque area to reveal the message. Fun for creating games, promotional materials, or surprise announcements that can be hidden until you're ready for them to be revealed. This material remains opaque until scratched off.Details:Gold colored (can be scratched off to reveal clear film layer)8.5" x 11" (21.6cm x 27.9cm) sheet size5 sheetsAdhesive backingFor use with Silhouette Portrait, Cameo and Curio (Curio requires Large Base)
