This was a set that we used for a few months.
Box - very good condition with a bit of shelf wear in one corner - see pic
Manipulative - all there and is excellent condition
Pencils - used but maybe sharpened twice max - most likely only once if any
Book/Textbook - I did check off items on the before and after tests with light hash marks and then I went back and easily erased. No other writing in the book - and the spine is tight. See pic of example of one of the three pages that I used and erased.
Flashcards - this was the item that was used the most. All flashcards are there - however, we got a bit overzealous and wrote 'mastered' on a few of the Addition fronts of them. Others have 1,2, or 3 stars colored in with a pink pencil. Then others have nothing. None of the subtraction have any stars colored in and half of the subtraction flashcards have not been taken apart.
Posters - never used - they are in excellent condition.
We were very happy with this curriculum.
