Kodomo Challenge Picture Book Box for 1-2 Year Olds Titles: Let's Go! Titles: Playing in the Pool Titles: Little Pig Man is Strong! Titles: Sleepy Train Titles: I'm a Little Squirrel Titles: Think More and More! Each book has 24 pages. Although for 1-2 year olds, my child enjoyed them until around kindergarten age. I read these to my child, so there is some soiling and wear, but there are no scribbles or major folds, and they are perfectly readable. Please refrain from purchasing if you are sensitive to used condition.
