I'm decluttering because I'm moving. Please note that the textbook set is not included. This is a device that pronounces picture cards when touched with the touch pen. It was working last year, but when I tried it again after a few months, the sound wasn't coming out. Both the main unit and the pen turn on, and the green light comes on, but there's no response. Changing the batteries didn't help, so I'm selling it as junk. The pen tip is cracked, so I suspect the pen is the cause of the problem, but I can't be certain. It was used by a small child, so there is some wear and tear. Please understand this before purchasing.
