The box is very tatty as you can see from the photos, the original pen is missing but everything else is there.
There are 3 double sided booklets full of questions/answers and the instruction book. The mini hand held computer still works, although the battery may need changing at some point. This should be easy enough as there are 2 screws on the back. There is also a small pad of original answer sheets.
The hand held mini computer was made in Japan.
Please feel free to ask any questions and I will do my best to answer them for you. Thanks
