This is a valuable cap that Japan Air System, now under the umbrella of Japan Airlines, collaborated with the Giants. The standard size is listed as 58cm, but it has an adjuster, so a few centimeters of adjustment is possible. It has normal signs of use, but I don't think there's any major damage. Because it's based on navy blue, it has a certain texture. Those looking for a near-new, pristine item should probably refrain from purchasing. It will be folded at the back of the head and shipped via Yu-Packet Post.
