This is a quite retro Giants cap. The tag indicates it's made in Japan. Size is 53cm. I don't know when it was made or the material. It's unused, but has been on display for a long time, so there is some soiling (please check the second image). Please refrain from purchasing if you are at all concerned. I cannot offer a discount on this item. It will be shipped via Yuu Yuu Mercari delivery service.
