We were fortunate enough to have personally known Mr. Kuroi. After speaking with his friends in Japan, we (origin USA) received permission to use Mr. Kuroi's name to pay tribute to him. We will be selling these items for 30 days. After those 30 days, all proceeds will be donated to his family in Japan. If you love drifting and what Mr. Kuroi has done for the sport, please show your appreciation.
