Measuring inside dimensions - 1 1/2" , Metal is flat. Outside dimension: 1 15/16". 3/16" thick. This is very smooth and highly polished silvertone / nickel metal, and it is flat on the front and back. The edges are softly rounded. It would be perfect for the center of a sexy top, or for the straps (be sure your fabric is heavy enough however). This is a nice, heavy weight metal - great for tote bags or big bags also. It's even pretty enough to use for jewelry or other fashion accessories. It has no seams or breaks in the metal. |
