This is a health pendant from Inate Seitai (Mutsu Seitai). It's a type from two generations before the current "Result" model. It is said to "adjust the energy balance of meridians through wave resonance," and is expected to have effects similar to acupuncture. I feel that my posture improves and pain symptoms are relieved! I preferred the older model because I was concerned about the current red Result pendant, which is one generation before the latest, as it was prone to cracking and the fittings easily came loose, so I had bought extra ones. The latest one has returned to the magatama shape. I don't know if the effects are inferior to the latest model, but I've heard that there is no superiority or inferiority in the waves even with model changes. I purchased this for 9280 yen. I've only used it two or three times since I bought it, (because I don't have a habit of wearing accessories and forgot about it) and have been storing it. I'm putting it up for sale in case someone needs it. There are no scratches, but it has been stored by an amateur, so please refrain from purchasing if you are looking for perfection. ^_^
