LG's promise to the G5 is kept

LG actually did make the Smart Case their G5's first leak showed.
So if you were hoping to buy it, you can! Good old LG.
And with this photo,. you can see in the top right corner of the packaging that is it says G5 SE, and that doesn't mean an iPhone SE goes in it. It may be a smaller version, about the same size as the iPhone SE, but we don't know yet.
