The box is old and has scratches and stains, but the contents are new and unused. This is a flashcard learning material, "Shichida Kanae-chan A (Japanese Edition)". It is designed for infants and young children aged 0 to 5 years old to develop vocabulary and memory skills. It includes 600 A5-sized cards featuring familiar nouns such as animals, birds, fish, and fruits. By quickly flashing the cards, it stimulates the child's right brain, and is expected to enhance high-speed information processing ability and instant memory. The words are written on the back of the cards, allowing for simultaneous input of both pictures and words. Thank you for looking.
