I use different hammers and stamps to "decorate" them and use them in the jewelry I make. It's much easier than breaking out the disc cutters. I hope this helps. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great value on crush washers *by M***N on Reviewed in the United States on May 21, 2024* A great value on crush washers!
