Honestly, metals don't do well outside and modern plastics do. I had the groundskeeper of a VT college tell me she was pleased that we were using brass for their donor bench signs. We weren't but that how good they look. This material does not pick up fingerprints and is quite sturdy. We use it for name pins as well as signs for those reasons. Not all the options in the color chart come in all sizes, the more common ones do. The most common size is 1/16."
