Purchased in March 2022 at Marui Imai Sapporo! Unisex. Worn about 5 times. Stored at home, and there are 4 small, inconspicuous stains on the front of the cap. Regarding the guarantee, I'm not sure which one is for the cap, so I can't include it. The size can be adjusted with the belt at the back. Please note that I may have overlooked something as I am a private seller. Thank you for your understanding. m(._.)m Please refrain from purchasing if you are sensitive to used items. Size: 57cm
