Apple iPhone 7 Smart Battery Case

I got this as a gift last Christmas, I only opened it to try on my phone for about 5 minutes then put it back in the box and never touched it again except to take these pictures. I upgraded my phone so I no longer have any use for this case. It was never dropped, scuffed, or anything like that because, again, I didn’t actually use it. In mint condition except for open box. I have never even given it a charge, so battery battery is completely unused, has 100% life of brand new.
