Save on this Silhouette - Heat Pen Set here at our online store. The Heat Pen is perfect for applying foil transfer material onto different surfaces for your projects. You can use it on materials like faux leather or cardstock. Instead of pressing the foil onto the surface, the Heat Pen transfers it with heat, giving you a cleaner, brighter, and longer-lasting finish. What sets the Silhouette Heat Pen apart is that it's cordless and easily plugs into your machine's carriage, making setup quick and hassle-free.
