I am selling two guitar picks: one actually used by UVERworld's guitarist, Katsuya, and one from the UVERworld 2014 document book bonus. The pick used by Katsuya shows signs of wear and tear, such as scratches and paint chipping, as it was actually used by him. I picked it up after it was thrown during a live performance. I believe it was a live show at Huckleberry. I think it was the "LAST" tour. I've been a Crew member for over 15 years, so my memory is a bit hazy, but there's no doubt that it was used by him. Please rest assured on that point.
