This is a set of two surfboard-shaped keychains made by ROCK INN for the YAMAHA Sound Carnival '83. These keychains are over 40 years old. This ROCK INN is from the Shinseido era, a rare find before it became Yamano Music ROCK INN in 2013. They have been stored unused, but there is some wear and tear, and rust due to aging. Please check the images for the condition of the items.
