For me the sets in this section are exceptional. Especially those with the remarkable petite tiles.
For instance, the travel case with fold-away racks. Or, my second purchase, the miniature rosewood box. Also the decorated boxes. Exuberantly Chinese or demurely Japanese.
And those of Western origin. Like the French Art Deco box, fitting perfectly in the Mah Jongg period.
Or, from England, the custom-made fake leather box with two front doors.
