These are CAREERING CHANSON R301 (YW) earrings, directed by Shota Matsuda. The material is silver 925 with a gold appearance, making them very cool. The post that goes through the ear uses 18K material, which is particularly resistant to allergies. The earrings feature the CAREERING logo and are unisex in design. I purchased them new previously and they are unused, but there is some slight tarnishing from being stored in the box, although they are perfectly usable. Many celebrities and famous people wear them, and CAREERING is also featured in OURs videos, so they are highly recommended for those with a high fashion sense. Celebrities who wear CAREERING: Daiki Tsuneta (King Gnu), Tomohisa Yamashita, Shun Oguri, Kenshi Yonezu, Kyary Pamyupamyu, Hiroomi Tosaka (3rd J Soul Brothers), Kazuma Kawamura (THE RAMPAGE from EXILE TRIBE), Yojiro Noda (RADWIMPS) (honorifics omitted) etc. PLACEBO / hare / lemaire / uniqlo / sacai / A.P.C. / UNDERCOVER / our legacy / ACNE / ernest w baker / yohji yamamoto / ryu matsumoto / auralee / jieda / maison margiela / balenciaga / martin lose / ion / y2k / Koenji / Shimokitazawa / Amemura / Nakazaki-cho / vintage clothing stores / vintage clothing / Masaki Suda / Ryo Narita / Kota Fukami / adidas / Adidas / puma / Puma / nike / Nike / Miyuki Arihara / Aimyon / patches / badges / dairiku / kolor / noill / howday / goffa / sullen tokyo / vintage / mode / military / heel boots / 11747391 / our's / Pokers / 80s / 90s / 00s / vintage / vintage / cowhide / leather / military / American casual / silver / domestic brands / import / designers, etc. are welcome.
