CLOVER by CLAMP Complete Set of Volumes 1-4, First Edition All volumes have been stored with vinyl covers after purchase. As these are first editions from 30 years ago, there is some yellowing. I feel the yellowing is relatively minor considering the age (the second photo is from the top, and the third photo is of the sides), but please refrain from purchasing if you are concerned about this. Please understand that these are used items. No pets, no smokers. Instant purchase is welcome.
