These are for the third edition.  We purchased the whole set of Fix It! books and did not use the last three.  The only reason these are not listed as "NEW" is because they have been sitting on a shelf for years and I'd hate for someone to get them and find some minor scratch or something.  The covers are nice and clean, though, and as we never used them there is no writing or highlighting inside.  I took a picture of a page inside each one so you could see.
