I love the size of these clasps. They aren't too big, or small. I think they are easy to use and of good quality.
I like this size spring ring a lot. I think it's small enough for delicate work but easier to use for bigger/older hands than the 6mm size. Lobster clasps are my favorite, but these are a very nice alternative at an affordable price.
I use these spring rings for lighter weight beaded gemstone bracelets and they work really well. I love the closed loop as it saves soldering for security - one step skipped!
Great for crafting
