Fuji Yacht's highest-grade series, Nano Wave, a gakuran (Japanese school uniform) top and bottom set, size 170A W70. This is an absolute bargain if the size fits! Fuji Yacht's Nano Wave series is characterized by its jet-black color, which is significantly different from Fuji Yacht's X series, J-PROUD series, and even polyester 100% school uniforms from brands like Kanko and Tombo. If you only buy the top, the color won't match with slacks from other series, resulting in a mismatched look. Therefore, we highly recommend purchasing the set. This product can be washed in a regular household washing machine. (Be sure to put it in a laundry net.) This item is a new, unused, long-term storage item, but it is in very good condition, with no noticeable damage or stains. The W70 slacks have not been hemmed. *Because the same material as the current "nano wave premium" model is used, the black color is the same deep black as the current product. The nano wave premium is a later model, and this nano wave has a slightly more relaxed silhouette. The premium is slim-fitting and has more stretch, but this product has a basic fit. Fuji Yacht school uniforms are durable, and the fabric is sturdy, so you can wear them for a long time. 70% polyester 30% wool The item will be shipped in a red box, placed in a plastic bag, and wrapped in bubble wrap.
