{"product_id":"gold-closed-box-solder-on-clasp-3mm","title":"Gold Closed Box Solder-On Clasps – 3.0mm","description":"\u003cp\u003eThese 2-piece tongue-and-box closed box clasps with figure-8 safety are designed to be soldered directly onto chains or bracelets. Unlike open-style clasps—where the chain or bracelet slides over the top of the clasp, partially concealing it—these closed box clasps are complete boxes that attach to the ends of the chain or bracelet, leaving the clasp fully visible. The 3.0mm size makes them well suited for fine chain and bracelet work requiring a secure, clean finish.\u003c\/p\u003e\u003cp\u003eAttachment is versatile: these clasps can be torch soldered or joined using a laser welder, PUK, or Orion spot welder.
