I bought this for around 2,500 yen, hoping it would be educational, but my child wasn't interested. I'm offering it for sale in the hopes that someone else can use it. Everything in the first photo is included. The outer box and instructions are not included. The number and calculation cards are double-sided. I'm not a professional, but I've laminated them and rounded the corners. Although it's hardly been used, there are some minor scratches, possibly due to being made in a foreign country. Please be aware of this. Feel free to ask any questions you may have. If you have no questions, you are welcome to purchase it immediately without commenting. Thank you.
