This is the original MX Master mouse (i.e. version 1) in a no frills cardboard box. I bought this some time ago versus the slightly more expensive version in a color box like what you would find on a store shelf. Master 3 is a newer version as you can see for example the shape in front of the buttons. The other technical differences between Master (1) and 3 I could not say.
