How to Open
How to open: hold the stick buckle on one end, press the switch on the other end — look for the small concave circle with horizontal stripes — then pull out the rod buckle. Close by pushing the rod back in until it locks.
Material & Durability
Copper base metal with a gold or steel plated finish: bright, even, and resistant to daily wear. Waterproof and sweatproof, and not easily faded.
DIY & Applications
Use the clasp on necklaces, bracelets, and anklets as a decorative connector — the oval body works as part of the design, not just a closure.
