This is a collaboration limited edition cap "SHAKA Doro-zome" from Chojiro Seisakusho, nataldesign, halftrack products, and TENGU's Advenrure is out there. Brand new, unused. The size is free size, and it can be adjusted by tightening the string at the back of the head. The fabric is similar to that of a judo uniform. The natural dyeing method, doro-zome (mud dyeing), provides a unique texture. You can also enjoy the aging process. This is a very valuable item, and it is unlikely to be available new in this condition in the future. Please understand that this item has been in someone's possession before purchasing.
