Origami and Kirigami Books for Children These books were used during my childhood, so there may be signs of aging, minor scratches, and stains. There are no markings on any of the pages. They are still usable, and I hope they can reach someone who needs them. - Book Title: Let's Make and Play Origami for Ages 5-7 - Book Title: Wonderful Kirigami By Kazuo Kobayashi Thank you for looking.
