As I understand it, the set is distributed by Xiaomi in partnership with Wiha. What's written on it is not that important. I can only say that the set is very well processed and absolutely top for the price.

No, unfortunately not yet, but it will come soon...I promise...

The screwdriver handle is magnetic and thus the bits also hold magnetically, all of them of course. The housing is also magnetic and the bits are reliably held in place, but very easy to grip. The product has a high quality and noble finish. It is a real pleasure to screw with it.
