This is a set of "Space Ace" in 5 volumes, originally published in Shonen Book, and "Shonen Sharp" in 1 volume, which was published in school magazines. They are reprint editions published by Apple BOX Create. Manga Shop also published these, but the Manga Shop editions are reprints from the magazines. The Apple BOX editions are reprints from "Shonen Book Comics," so there are differences in the panel layout and the presence or absence of certain drawings. Overall, I think the Apple BOX editions are more carefully and beautifully reprinted. I believe the reprint of "Shonen Sharp" is only available in the Apple BOX Create edition. There are some age-related light spots on the top, bottom, and side edges, but they are in beautiful condition without any damage. "Shonen Sharp" has a slight crease, but it's hardly noticeable. I've checked them thoroughly, but there might be some minor oversights. Please forgive me if there are any. Please understand that these are used items and only purchase them if you accept their condition.
