Thank you for viewing. I am selling a set of the "Why? How? Science Stories" series for grades 1-5. There are noticeable scratches and stains, but there are no problems with reading them. Please understand that these are items stored at home, and I would like to sell them to those who do not mind such scratches and stains. Immediate purchase is OK. Please note that we do not accept price negotiations (discounts). Currently, individual sales are not possible. We strive for smooth and pleasant transactions, so thank you for your cooperation. *If you would like more detailed photos, please comment.*
