This is a set of 5 issues of "Gekkan Kagaku no Tomo" (Monthly Science Companion) published by Fukuinkan Shoten. The books are being sold because my child has finished reading them. The issues are May, June, July, August, and October 2021. There are some scratches and small marks on the covers, but the inside is relatively clean.
