This is a set of three binders containing issues from DeAGOSTINI's "Understanding the World Through Manga: That's Right! Social Studies Edition." The manga format, featuring historical figures explaining how society works, makes learning fun for children. This is particularly suitable for children in upper elementary school and older. I collected these about 20 years ago, but didn't have time to read them thoroughly. They have been stored on a bookshelf for a long time, so the binders show signs of wear, including dirt, sun damage, and some damage. The inside pages are relatively clean, so I believe you can still make good use of them. I originally purchased these weekly and stored them in the binders. I believe I have included everything I bought, but please understand that I cannot guarantee that every single issue is present. I have taken some photos, so please take a look. I disinfected the coated covers and checked the pages inside. I only took photos of pages where I found dirt or significant damage, so please review them. I am a casual inspector and did not check every page individually, so please forgive any oversights or missed details. Please understand that these are used items before making a purchase. I am selling these to declutter. I hope someone will take them and enjoy them. How about them for the winter holidays?
