This is a set of 40 paperback books. Please refer to the image of the spines for the titles. I read them once and then stored them in a cardboard box, so I think they are in generally good condition. I have handled them with care, so the overall condition is good, but they are still used items, so please refrain from purchasing if you are sensitive to this. #Takarajima SUGOI Bunko #Underground #Economics #Novel
