I purchased this last winter, but it didn't fit, so I'm selling it. The size is M, but it's a bit oversized as it was a little large on the seller (173cm, slender build). Generally, there are no stains or fraying, so it's clean, but there may be oversights due to human inspection. Please be aware of this. Also, please refrain from purchasing if you are overly concerned about details. We do not accept claims. Please purchase with your understanding. Color: Blue系 (Blue-based)
