Picture books, CDs, and books. I purchased these in 2020 from a previous seller who bought them in 2016. The child actors seem to be from an older version, but the content appears to be the same as the newer ones. At my house, we only used the first half of the numbers a few times, and some of the second half are almost unused. The previous seller used about six of the sticker seals, with most of them unused. The Sing Along books have some wear and tear, such as paper creasing and small scratches, but there are no tears.
