※Please refrain from listing items by copying parts or the entire product title and description, or from selling copies of teaching materials.※ Hishiesu Seibunsha Sansu Box [Suuzu Block] [Kazuzu Block] Brand new, unopened, 2025 edition, with an official case. All contents are unused. There is no writing on the outer package. This is an authentic product that meets the safety and security standards, as it is a teaching material used in elementary schools nationwide. It is used in the first grade of elementary school, but even kindergarteners can enjoy learning numbers with their parents. It is also ideal for preschoolers as a supplementary, advanced, or educational material. I store it with care, but due to friction with the box, there may be some minor scratches. Thank you for your understanding. Due to the thickness, the cushioning material will be a thin type. If you need it urgently, you can change to Rakuraku Mercari delivery for an additional 100 yen (same-day shipping, arrives the next day at the earliest in Honshu). In that case, we will ship it flat with the case open, so please send a message in the comment section beforehand. I hope it will be helpful to those who need it. #SansuBox #ArithmeticSet #SansuSet #EntrancePreparation #SansuLand Hishiesu Seibunsha Sansu Box
