This is the Shichida Method Dots Set. I purchased it from the official online shop about two years ago for the retail price of 19,250 yen. I used it about 10 times and then stored it at home. It's a waste, so I'd like to sell it to someone who will use it. All the cards are present! I tried to check the order, but there's a possibility that the order might be slightly off. Also, the outer box has some scratches and signs of use, but the cards themselves are not dirty. In addition, the small paper cases that hold the cards (with the day numbers written on them) show some signs of use, starting around day 55. The instructional DVD has never been opened. A "Dots" Winning Strategy Manual is included. I look forward to your purchase if you understand that this is a used item.
