- Brand: BLUE WORK - Color: Gray - Material: 100% Cotton - Made in Japan Length: 66cm, Width: 61cm Shoulder width: 66.5cm, Sleeve length: 56cm *Please note that these are amateur measurements, so there may be slight variations. This item uses a rare vintage knitting machine unique to Japan to slowly knit the looped back fabric. Due to the low productivity and the scarcity of existing knitting machines in recent years, the price has risen, and production itself has become difficult. This fabric is a valuable material that requires unique production routes and experience. It is said that it can be worn for many years because it becomes denser while maintaining its softness through washing, and eventually becomes like a part of the skin. While the production background is classical, the design has a modern feel with slightly dropped shoulder lines. No noticeable damage or stains were found, but this is a used item. We appreciate your understanding before purchasing.
