Thank you for viewing! Science Manga Survival Series - Set of 2 books ➮ Allergy Survival 1 ➮ Energy Survival 1 ※ Although these are 2-volume series, please note that this is only volume 1 of each. There are no scribbles, tears, or major stains, but they have been stored on a bookshelf for a long time, so there is some deterioration of the covers (minor scratches, wrinkles, etc.) and some bending on the top and bottom. Please check the images. ↓↓↓↓↓↓ Considering the above points, I would like to sell these to someone who understands that they are used items.
