This appears to be complete and includes original instructions. The box states 56 blocks to set #620 and there are 60 blocks. Sturdy styrofoam blocks in different colors. There are 4 longer blocks 13", 2 round halves and 53 smaller blocks 6" each. There is a single pieces as well. 7 small blocks are missing a connector and 2 smaller blocks are missing a corner piece. The longer blocks 1 is missing a connector and one corner is broken. 1/2 the round is broken on the inside. The broken pieces do not affect the play or building. The top of the box all 4 corners are ripped so basically it lays flat. The bottom part looks pretty good. Please view all photos carefully for complete content condition. All of my items come from a smoke and pet free home. Remember I list on other sales platforms!
