Tomoe's 100-bead abacus and a wooden Chiken (Cognitive Research) target hook board. Frequently appearing in elementary school entrance exams, it also helps to improve spatial recognition skills, such as line symmetry and point symmetry, while playing. I think there aren't many hook boards for sale, so I personally think it's valuable. I am selling it because my child has grown up. In my subjective opinion, it is clean with no noticeable scratches or stains. The abacus was also easy to hold because it had a handle. Cleaned with alcohol. There are no pets or smokers in the house. I would appreciate it if those who understand used items would consider purchasing.
