Suichuukas shift knobs were originally hand-made, using dried flowers trapped in clear resin, and was found in various size and shape. The Japanese word suichuuka 水中花 literally means "flower inside water". The Suichuuka fever really started in the 80s and the knobs were very popular among truck drivers. Later, they became Bosozokus and Japanese oldschool enthusiasts’ favorite accessory.
The authentic Japanese vintage flavor!
