Sawa Voters Embroidered Cap Color: Black Material: 100% Cotton Purchased used, but has been on display without being worn. The back can be adjusted with Velcro. Based on the design and tag, it appears to be a "T-Plus" series cap, which is used in the space industry. However, it doesn't have the NASA logo, and the material and fine details differ from currently available items, so the specifics are unknown. Please check the images for details. There are no noticeable damages, but please consider this a used item. To prevent damage to the brim, it will be shipped in a Takkyubin Compact dedicated box.
