This is a strong clasp, especially for it's size. I have used it on a delicate gold filled chain. Remember to slide apart, and not pull.
Good Strength for the size
I love to use these on tennis bracelets and other delicate jewelry. They are very strong for their size. I will use a bigger size for gemstones and heavier items.
14kt goldfilled magnetic clasp
These are the very best magnetic clasp. They're perfect in size and very strong. Works very well on bracelets or necklaces. Thank you for this wonderful product.
