Level 1, 2, 3 & 4 Hooked on Phonics learning system. Level 3 & 4 haven’t been opened. Level 2 has been opened but everything is there and in perfect condition. Level 1 has water damage on the big book and small books are missing.
These are cassette tapes.
I scanned one of books from level 4 to get the ISBN. There are more books.
