This is a valuable cap that Japan Air System, now under the umbrella of Japan Airlines, collaborated with the Giants. The standard size is indicated as 58 cm, but it has an adjuster, so a few centimeters adjustment is possible. It has normal signs of use, but I think there is no major damage. Since it is 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.
