This is the Ichikawaya original high-class mahjong tile set, "Sansu Hai First Ver." These carefully crafted mahjong tiles are made with meticulously selected materials. You'll be amazed by the incredible detail upon close inspection. I've kept them as a collector's item, so they're in excellent condition with hardly any signs of use. The "Sansu Hai First Ver." is a rare, out-of-print mahjong tile set, making it impossible to purchase new. It comes in an Ichikawaya original paulownia wood box. This case is also a high-quality item that was only included in the initial sets sold at the time. If you love the Washizu Mahjong style and are looking for a high-quality transparent tile set from that era, you won't want to miss this.
