【Brand New】 Thank you for viewing. This is a 30mm floral concho made by KC's. A Swarovski crystal glass is used to decorate the center of the floral design. The Swarovski color is crystal, which is the most popular and standard color of the company. Deerskin is inlaid inside the concho, and can be seen peeking out. The screw is the type that is tightened with a hex wrench. ★Price negotiation not accepted
