This is a popular and rare long-sleeved T-shirt featuring a panther, a collaboration between Kyosuke Himuro and Chrome Hearts. It was stored in a case, but because the case was translucent, it was exposed to sunlight and has become discolored as shown in the photos. It seems that you can remove the discoloration (yellowing) by choosing the right detergent, but I haven't tried it, so I'm not sure. I will sell it as is, so please purchase it only if you understand and accept the condition. It has only been worn once.
