Thank you for viewing! This cap was made from persimmon-dyed fabric, likely from a large fishing flag that was actually used in fishing. Dyeing the colorful fishing flag with persimmon dye gives it a calm and tasteful color. This is a unique, one-of-a-kind item with effective stitching. The fabric is sturdy, so there is no lining. A thick, fabric adhesive interlining is applied to the brim, but it is soft. The seam allowances are taped to prevent fraying. The size can be adjusted with the adjuster at the back. Material: Outer: Cotton (large fishing flag) Size: Inner circumference: 57.5-60cm Side crown: 17cm Brim (visor): 8.5cm (center front) Measurements are approximate and taken by a layman with a measuring tape. Please allow for some margin of error. If you have any questions, please feel free to ask in the comments section. Although the cap has not been used after being processed, the large fishing flag that was actually used in fishing has been persimmon-dyed at home. There may be some stains, color fading, and uneven dyeing that cannot be completely removed. If you are concerned, please refrain from purchasing.
