I bought it from a local brand here in Romania and has a generic name, like Doctor Shield Fantom, but i searched and it's similar (or exactly the same) as the Mgnaooi Magnetic Case that can be found on amazon:

It does add a slight thickness to the phone as it has a lip over the screen and back side.
