This is a natural stone strap. It uses cracked crystal, crystal, brecciated jasper, and onyx. The end parts use double rings, so you can also replace them with a carabiner that fits the ring size. (Change available for +50 yen (plain round type). Please comment.) I take pictures to look as close to the real thing as possible, but the actual color may differ. I use overseas beads (natural stones). Please be aware of cracks, inclusions, initial scratches, and scratches. Thin wire is used in some parts. I make them carefully, but they are not as strong as mass-produced products, so please do not pull them strongly. Please purchase with the above in mind. It will be waterproofed and shipped in an envelope.
