This pen is a “must have” fuser’s tool. Any marks made with this pen hold during assembly without smudging and burn completely away when fired. Now you don’t have to guess when placing your pieces, you’ll always know if your glass in lined up evenly and be sure exactly where the center is located. More durable than a Sharpie, has a fine tip and black ink.

A tip from Carmen – To keep your pattern lines in place when you are using a grinder or wet belt sander use a Staedler Pen and smear a thin layer of Vasoline over the top of it. The line will hold until the water works are done. Remember to clean the Vasoline off you glass with soap and water.
