Silhouette heat foil is applied permanently onto select project surfaces using the Silhouette heat pens. This can include surfaces such as faux leather and cardstock. As opposed to pressure-based foil that is pressed onto the material surface, heat foil is transferred via heat, thus providing a cleaner, brighter, more durable finish.Details:Silver3" x 33ft.
