This is a cap from the collaboration between Aolabu and Lee. It was a limited edition and is not widely available. I used this once at a live performance, but it's clean with no stains, I think. As this is a rare item, I'm selling it at the original price as much as possible. Please feel free to comment if you have any questions. #Aolabu #Skypeace #Jintan #Teokun #Maataso #Kasu #Kasuchan
