I used it once, but I didn't have much opportunity to use it, so it's still in good condition. I had it on display. This is one cap made by TATOO STUDIO YAMADA. Daiki Tsuneta of King Gnu wore this, and it's a sold-out item that will not be restocked. There is no particular feeling of use, but if you are concerned, please refrain from purchasing. Color: Black系 (Black-based) Stains, tears, odors, etc.: None
