This is the high-end mahjong tile set "Zuiun" from Mizuno Maruichi. This set belongs to the high-quality category within the Maruichi brand and comes in a special case designed for premium tiles in excellent condition. The tile size is 26 x 19 x 16.5 mm, with a trapezoidal interlocking design. The best feature of these tiles is the substantial weight, which provides a satisfying feel. They haven't been used much, and the backs of the tiles are completely free of scratches, making their condition superb. The gold leaf is also vividly preserved. The "family crest-inscribed Ii-pin" is particularly stylish.
