This is a Maebashi Ikuei High School baseball team support cap. There are no stains, but it shows signs of use as shown in the photos. After washing and drying it, I had it on a stuffed animal, so the back is a bit rounded. However, as shown in the photos, if you put it on your knee as if it were a head, the rounded adjuster area will fit snugly! Please refrain from purchasing if you are concerned. The crown part is made of sponge material with shape memory, so it will return to its original shape. It doesn't take up much space in your bag and is convenient to carry. Price is not negotiable.
