Hi. This is a small collection of 4 Leapfrog Tag Junior books with the pal reader and cord to connect to a PC. Books are of Toy Story, Thomas the Train and a couple Sesame Streets. One book is only 10 pages but the others are around 20 or more pages. The pages are like dry erase boards. These are lightly used with light wear. The pal reader has been programmed for these 4 books and will read all 4. It works by simply placing the little bear on various parts of the pages and it will read them to you. Takes 2 AAA batteries (not included). I don't believe these can be upgraded anymore. The last I looked they are no longer on the website. Please see pictures for details. Thanks for looking.
