This product has been used on several of my jewelry projects. It has been a durable, reliable clasp.
Silver filled lobster clasp
These are the perfect size for my creations and work very well.
These lobster clasps look nice, and are a good size. Unfortunately, they are very difficult to open, and expensive. These really aren't worth it. I prefer the silver plated lobster clasps of the same size. They are a bit shinier and much easier to use.
