Go board game, travel size with magnetic pieces and rotating trays. Amazingly, it was made in 1973 by Nintendo, as part of their Mini Game Series. Very rare item. In great condition, plastic is clean no cracks, no discoloration. Magnetic game surface also very clean. Rotating trays are very tight. Hardly played condition. There are 45 black pieces and 47 white pieces. I will assume there were originally 50 of each.
