This is a haori string with a double-layered pearl design and a clasp. It can be hooked onto the collar buttons and worn like a necklace. I am not an expert, so I cannot determine the authenticity of the pearls. They glow blue under a black light. The length is approximately 12cm and 15cm, in a double strand. The pearl size is 6mm. There are no markings on the metal fittings, and they react to a magnet.
