BJ Classic Collection COM-510N-NT 48□21 (BJ Classic). C-30-1 Kurosasa Gold These glasses have prescription lenses, so lens replacement is recommended. I purchased them in September 2025, but they don't suit me, so I haven't used them much. This is a very popular model worn by many celebrities, including Satomi Ishihara, Gen Hoshino, Ryosuke Yamada, Mizuki Yamashita, and Erika Mori. BJ Classic COM510NNT COM510N COM510 Case and cloth included. Thank you.
