Popular youth manga "Cells at Work!" complete set of 4 volumes. - Title: Cells at Work! - Volumes: Set of volumes 1-4 - Author: Akane Shimizu Thank you for viewing. It is also possible to purchase as a set with other manga I have listed. I have stored them with transparent covers. As these are manga purchased several years ago, there may be some sun-fading, scratches, stains, and folds. Please understand this before purchasing. I will put them together in a waterproof bag and ship them in an envelope or a dedicated cardboard box.
