The Vintage Pocket Pen Microscope is a unique and compact microscope tool designed for precision and magnification on the go. This microscope pen can be easily carried in a box, making it convenient for inspections and examinations in various settings, including vehicle parts and accessories. With no warranty, this microtool offers a reliable and practical solution for detail-oriented tasks that require a close look.

I have no other details, it is part of some goods I inherited, as far as I know it is quite an old piece. I do not know the magnification strength but when looking at objects it magnifies really well.
