I believe this is Kansai-style typeface. It's from before 1989 (Heisei year 1). The opening of the stick bag was open. The weighing photos of the non-weighted tiles are reference images and are not the product itself. As you can see, the tiles are unopened, but the outer cardboard box is missing, so I've listed it as "Like New". The Yakuman (winning hand) guide has stains and yellowing. 144 tiles total: Yakuman Tokujyu (Extra Heavy) = 2311g, 1 tile = approx. 16g Yakuman Jyuuryou Hai (Weighted Tiles) = 2055g, 1 tile = approx. 14.25g Yakuman = 1832g, 1 tile = approx. 12.7g I'd like to compare them one by one and hold them in my hand, but I won't...
