Clasps for jewelry / federing 12mm platinum 1pc ZAPSR12PL

Platinum-colored federing clasps, size 12mm. Clasps for thicker bracelets and necklaces with stones. Federing is a fastener that works in a similar way to carabiners, except that the movable element is hidden from the tube. This gives a greater guarantee of safety and works well where there are elements that could slide out. The clasp finishes the jewelry very aesthetically.
