All 33 volumes of Blue Lock and all 6 volumes of Blue Lock: Episode Nagi, a total of 39 volumes, are first editions with original bands and book covers. As you can see in the photos, volume 7 has noticeable yellowing. Volumes 1, 2, 3, 4, and 6 have minor yellowing. Are any collectors interested? I am also selling other manga, so please take a look.
