I used this item twice after purchasing it new, but I'm selling it because I've been using automatic tables since then. This is the AMOS Max, which is already discontinued. The outer box has some scratches and damage, but the inner box and accessories are complete, and the tiles are in very clean condition. I believe it is of the same quality as the AMOS series used in the M-League. Among the tiles for manual stacking, it has the closest texture to those for automatic tables, and there are no current products with the same size and weight. Body weight: 3.4kg Tile size (per tile): 21 x 28 x 16.5mm Tile weight (per tile): approx. 16g As a bonus, I'll include an AMOS compass and colored score sticks, which are convenient when playing mahjong manually. Please understand that this is a used item before purchasing. Thank you. Mahjong table type: Mahjong tiles Manufacturer: AMOS
