ERG Sports necklace for athletes gives edge Japan

This is a UNISEX balance and strength necklace for athletes or daily use for an extra legal edge. Sought after hard to find. Decided to sell mine. Originally from Japan retail was $200usd. I believe its titanium and polyester. 50cm Used a few times. Has some pill but will remove it before shipping. Stated that it can be hand washed. I can’t read Japanese for more details but there is a pamphlet inside and info on the web. Used by many celebrities and athletes. ❤️bundle to save.
