MVPen - Turn Your Handwritten Notes into Data

I received this from an acquaintance a few years ago, but I am listing it for sale as I have no use for it.
I have not been able to confirm its operation. (Treated as junk.)
Please understand and purchase.

*The box has folds and tears due to age-related deterioration.
The listed images are all that is included in the sale.
*Dedicated case is missing.

This allows you to view, save, and utilize the content written with the MVPen on a notebook on your screen.
It can also be used as a ballpoint pen on a regular notebook, so it has the function of leaving a notebook in your hand.
