These non-magnetic tube clasps have a built-in self-latching lock. Both the tubes and the soldered loops are made of stainless surgical steel. This provides a very secure closure for your 3-strand jewelry designs.
Clast size: 20x10mm including the loops.
Very strong, stainless and tarnish resistant
Surgical steel is highly tarnish resistant and a great alternative to sterling silver. If you need jewelry findings that last and does not cost too much, surgical steel is a great choice.
