German Glazing Nails - 100
German Glazing Nails are wundervoll (wonderful)! They are made of steel and they keep a sharp point. They don't bend at the tip like horseshoe nails. Since you won't be throwing them away when the point gets bent, they will be less expensive to use in the long run . . . . and decidedly less frustrating.
If you took a lead came class from Tommy G. of Manhattan Stained Glass, you would learn about German Glazing Nails. He would tell you, "These nails are expensive, but they're worth it."
