Blue Metallic Laserfoil! Add elegance to any document printed on a laser printer or a copy machine. Print document from a laser printer or copier. Place the foil face down, shinny side up, over the area you want to color. You can now iron it on with a very hot iron. Wait 30 seconds and peel off. You can also run through a laminator to adhere the foil. Laser Foil works by sticking to the plastic in the toner. Will not work on inkjet printers. Each size roll is 8" wide.
