The new Mona Lisa Adhesive Pen is designed to allow the artist to add small amounts of metal leaf to a project, without using a brush. It is also great for writing, and adding designs to projects. Use it like a pen to write or draw designs on a variety of surfaces. After 5-10 minutes, press metal leaf onto the project and then gently remove the excess leaf. The pen has dual tips just pull the bullet tip out of the pen, flip, and it becomes a chisel tip. The two tips make the pen perfect for creating embellishments, fine detail, signatures, calligraphy, lace design, ornaments, and more. The pen's adhesive is both non toxic and acid free.
