Set of 4 books. All with obi (paper bands). - My Room Got Cleaned Up - My Room Got Even Cleaner - My Motivation Came Back - I'll Finally Do This By: Watanabe Pon Some were purchased new, and some were purchased used. After purchase, I put them in clear covers and stored them on the bookshelf. Due to the thickness being close to the limit, I will take waterproof measures, but the air padding will only be on the corners. Please understand this before purchasing.
