I use them to hold pieces of leather together while the glue dries and they are great. The pressure is enough to hold the pieces together, but not enough to pinch the skin. Plastic tips prevent scratches and rust (when they get wet) and make it easier to remove wet glue. I thought 100 grand was a crazy amount but now that I have it I wouldn't buy any less. I mean $0.17 a clip! How can you go wrong?
