You can't own the Monster Hunter XX Nintendo Switch Ver. Pack because pre-orders have sold out in Japan already, but just in case you were wondering what the packaging looks like, feast your eyes:

The pack includes the Switch console, a copy of Monster Hunter XX and a dock with a unique design based on the popular series.

Capcom stated at the time of the announcement that the Switch console would also have a special design, and you can see that in the image below:

Unfortunately, Capcom has already stated that it won't be creating any new Japanese stock of the bundle, and there's no word on whether or not the bundle will be coming to the west. Still, it's nice to look at.
