I'm making a name-tag board for the Junior High Ministry @ my church. It will be carted to the beach, among other places, and needs to hold up well to the elements. I ordered these "brass" binder clips from Rockler. Got them in today and my friend the magnet tells me that there is not a whole lot of brass content in these light-weight puppies. Soooo, they (all 55 of them) will be returned in tomorrow's mail, and I'll keep looking. Any suggestions?
