How about reading them all at once during summer vacation? ~Product Description~ I was keeping them as a collection, but I'm letting them go to organize my bookshelf. I read them once after purchasing and stored them in a dark bookshelf, so I think the condition is not bad for a used book. You can see some yellowing on the manga books, please check the images. I think you can still use them, but please purchase only if you understand that they are used items.
