This is one year's worth of Popikko Kiidori. For preschoolers, ages 3 and 4. These have been used, so there are folds and stickers attached, but no writing. The supplementary materials are not included. Also, some pages have been detached, so there may be missing parts. Would be great for those who want to get a feel for it or try it out. Will be shipped in a waterproof package using recycled cardboard. Please understand that this is a used item before purchasing. - Series Name: Popikko Kiidori - Volume: All 12 volumes - Target Age: For preschoolers, 3-year-olds - Content: Picture book/Activities - Theme: Zoo - Illustrations: Colorful and cute characters - Language: Japanese Thank you for looking.
