Mahjong Mats That Know Their Tiles

Field notes

The product is sized around a particular play setup: four walls of nineteen tiles, racks, and a discard pool, with the maker arguing that 33 inches leaves card-table corners clear. Neoprene is presented as both a playing-surface choice and a shipping solution because it folds without retaining a crease. Buyers can choose whether to include table-reference text, and the page explicitly separates that common-practice material from the National Mah Jongg League’s copyrighted annual card.
