18k Yellow Gold Invisible Flat Hinge Clasp

The quintessence of minimalist elegance. This clasp stands out for its entirely flat design, which allows it to sit perfectly on the skin without creating any thickness. It is the ideal choice for a clean finish and absolute comfort.

Its ingenious hinged mechanism ensures an almost invisible closure, transforming the clasp into a stylish link that discreetly extends the line of your jewelry.

Its greatest strength? It installs without any soldering. Simply open it, slide in the links of your chain, and close it with a simple "click" for a professional and secure finish.

Made of 18-carat yellow gold (750‰), it offers the timeless warmth and shine of traditional gold.

A Versatile Jewelry Piece: Clasp, Connector, and Bail

This clasp is a true Swiss army knife of jewelry, designed for much more than just closure.

• A Minimalist Style: Its flat profile is perfect as a decorative clasp for contemporary creations where discretion and purity of lines are essential.

• Charm Connector: Its openable function makes it ideal to become the base of a modular jewelry piece. Hang your pendants on it for a style that changes according to your desires, without any tools.
