This is a TOSJ TOKYO CAP sold exclusively at the 5lack one-man live "Sono Saki no Hanashi" held at the Itabashi Cultural Hall on September 19, 2025. The embroidered side patch gives it a special feel, and 5lack himself wore it during the live, making it look really cool, so I bought it. I haven't had a chance to wear it, so I'm offering it to a fan. The size is free, and the condition is new and unworn. 5lack fans, don't miss this opportunity.
