Product Description This sports necklace was created based on the opinions and requests of professional athletes in various fields such as track and field, cycling, skiing, and golf. SEV is built into the head part, supporting athletes who aim for higher performance. It has a stylish horizontal head design and is made to fit closely around the neck. This is the model worn by Fujiwara at the Olympics. It is an essential item to add a touch to your running fashion. ＜Difference from SEV Metal Rail Si＞ By changing the silver 925 chain used in SEV Metal Rail Si to a stringer type, the lightness when worn has been further enhanced, and the fit has been improved.
