Metallic foils provide you with a metal-like shine in a variety of colors. Your project is foil stamped with a non-tarnishing metallic finish, with a shiny, reflective surface that catches the light. Metallic foil's effect is most noticeable against a dark or matte paper stock. Gold and silver are the most popular, but metallic foils are available in a variety colors. If you are looking to add a lighter color to a darker stock, we recommend using a foil.
