Guess what’s this

Can you guess what is this item in the photos below?

This is a USB flesh drive, pocket memory made in steampunk style. It is enclosed in a wooden box, decorated with copper, with some tiny measuring device and the same tiny flywheels. It comes with the appropriate “vintage” holster. Inside you’ll find 8 GB of memory – not really impressive – but it costs $ 300.

It is a bit expensive, but I’m sure all fans of steampunk will be more than happy to give this amount of money to have such a stylish and unique USB flash drive. What do you think?
