Judging by the bindings and clean Interiors I don't think these books were ever used however they have been stored for many years in dusty conditions, the tops of the books have some soiling/spotting, see photo, but the interior pages are clean. The outer box has some wear but is intact. Great for someone who just wants to use these books and isn't concerned too much about appearances. Three Mass Market sized paperbacks, dictionary, thesaurus, vocabulary builder, in box set.
