This is the METAX, a high-end model necklace from Phiten. Of course, it's genuine! This is just my personal opinion, but it really reduced my stiff shoulders! Also, I no longer experience the symptom of not being able to turn my neck due to a stiff neck! Please take this opportunity to get one. It will be shipped by Nekopos with bubble wrap, without any accessories. RAKUWA Neck, used by Hina Hayata (table tennis) and Yuzuru Hanyu (figure skater) ● The spherical pure titanium clasp is polished with a "mirror finish" and laser-engraved with the "Phiten" logo. ● Easy to put on and take off with a magnet type. ● The thin cord is easy to fit around the neck for both men and women. ■■Specifications■■ Size: 45cm Color: Earth Color Material: Cord (outer fabric) / 100% polyester, Cord (inner core) / elastomer Clasp / titanium, magnet, stainless steel Technology: Metax JANCODE Earth Color: 4940756411186 (45cm) Search words phiten Phiten Athlete Ambassador Daichi Ohsera Yuzuru Hanyu Hina Hayata Teruaki Sato Yoshihiro Maru Tetsuto Yamada Kona Takahashi Yuki Yanagita
