A picture book set that teaches the techniques of string figures (Ayatori) and origami. - Title: Traditional String Figures (Ayatori) - Title: Traditional Origami - Contents: Picture books introducing the techniques of string figures and origami - Target age: Children - Language: Japanese Thank you for viewing. This was delivered as part of a Dowa-kan book subscription. It's a book so detailed that children can understand it on their own. My children often did origami and string figures at their Montessori school, so this book was very useful among the children. There are no noticeable stains, but it has been read well, so it is a used item. Please understand this before purchasing.
