For the price these are very good quality. They are sturdy, and I've had no problem working with them. They're not as round as I would have liked, but most of them are serviceable. However, the blue film that covers the metal and is stuck underneath the nut is a big problem. If these were only for personal use I might not care that much, but I bought them with the intent of using them to display cross stitch gifts, and that blue film really has me questioning if I can use them for that. It's annoying to have little shreds of blue film poking out from under the nut. I tried both a razor blade and a pin to remove the film, but those still didn't remove all of it, and they somewhat scratched the metal thus defeating the whole purpose of the protective film in the first place. The stress of trying to remove the film has really gotten to me, and if it wasn't for the film I would have given these a higher rating.
