Kodomo Challenge Hopp This is an 8-book set from the April 2023 to November 2024 issues. These are picture books with educational content for 3- and 4-year-olds. These books were read by a child, so there may be some wear and tear, such as creasing, scuffing, and minor damage, but overall they are in good condition as the child was getting better at reading. There are no markings. Thank you for your understanding.
