The bag is tailored for OnePlus One 'A001'. There is so little Game found that an additional Bumper or even one of the original Back Cases (the money are not worth the way - my has the second day already had a stress-cracking, on the third day came yet this and that was the reason me to get this bag, among others).
What I miss: The bag does not provide closure. This is of course from the description and the photo out already apparent, although in my opinion it is missing after and so I subtract a star.
