These are original, vintage Mizuno Maruichi (MVC brand) mahjong tiles. They are all-black tiles, with a comfortable weight that makes them easy to hold. The font used also reflects Maruichi's attention to detail. The tile size is 25.5 x 18.5 x 15.5 mm. In my subjective opinion, I have kept these in my collection with great care, so while there is some rust on the handles, the overall condition, including the case, is in excellent condition. The lustrous black backs of the tiles are very beautiful. These are high-quality tiles from the "MVC" Mizuno Maruichi brand, and are undoubtedly excellent mahjong tiles.
