It looks like a pen, but it's actually a precision instrument. I believe it was a prize from something like a memory technique course over 15 years ago. The only documentation it came with was a single image. It's a pen-shaped voice recorder, but according to the instructions, it can only record about 10 seconds per channel, which is a rather underwhelming spec by today's standards. Therefore, the image I have is that it's a mini-present for a child who isn't yet allowed to have a smartphone, or perhaps the batteries are the main thing, and the pen-shaped voice recorder is more of a bonus.
