This is a set of precision electric screwdrivers in a pen shape. It's powerful for a pen-type screwdriver and is USB Type-C rechargeable. I bought it to build my own PC, but I ended up ordering a pre-built one and haven't had a chance to use it, so I'm selling it. It can be used for assembling furniture, as well as for precision work on smartphones, game consoles, and even building your own PC, making it suitable for any purpose.
