This is the official cap of the Hokkaido Nippon Ham Fighters baseball team based in Sapporo, Japan. It was purchased at New Chitose Airport and I consider it new, though I did remove the tag (included) before trying it on at home and found it to be too big. Although adjustable, it has a size range of 57 to 61 centimeters (22.4 to 24 inches). You can tighten it to fit a smaller head, but then the Velcro strap sticks out farther. The bill of the cap also seems a bit on the large size, which is why I placed a ruler in a couple photos for scale (ruler not included). I'm unsure of what the brand is, but it does say "Official Products" on the tags.
