Chiken Program C-15 Purchased new and used in a preschool classroom. Includes a home guide, so you can nurture your child's intellectual development by playing together at home. The number on the box has been corrected. (See photo 4) There are circles written on the paper, and wrinkles. (See photo 5) If you don't need the box, it will be 500 yen off. I checked the contents and they were all there, but please understand if I missed anything.
