Purchased about six months ago and used for copying, so the paper is unused and clean. The answer booklets are mostly clean, but some have wrinkles or stains. There is some wear and tear beyond what is shown in the photos. The green cover is also clean, but there are some minor scratches and warping. The plastic wrap is not included. Originally an 8-book set, but one book is missing (Common Sense). Also, the first page of Observation Skills is missing. Recommended for preschool and kindergarten children.
