They are basically unread - not one of the books has had a name filled in and I opened all of them to find that there was 'bend resistance on the outer cardboard covers which only happens when a book hasn't been opened/read. The only thing I'd mention is that there was some dust along the top ridge of the page edges from storage. I have cleaned this off, but some residue may have escaped into pages. From my thorough inspection, this may have happened on a small number of the books, most are mint.
The unpacked weight is over 5kg - postage and packing costs reflect this with adequate insurance included.
