Artbeads is the only place I buy any gunmetal from. They always have what I want, and it's very good quality.
I've already started using these rings. Good quality
Some of the jump rings were un-closed
Some of the jumprings in this order came un-closed, and some of them were not aligned properly when they were fused together, making for a weak link and a sloppy look. This wasn't an issue with many of the rings, but it's something to watch out for. The finish on the rings is attractive and seems durable so far.
