These pretty much speak for themselves; they're replacement 3rd party Xbox Series controller battery covers. What makes these different than the ones that some others offer, is that occasionally theirs will have an outline where the Xbox logo goes. Unfortunately since these are aftermarkets, thus that logo can't be there, and manufacturers can sometimes tend to be sloppy with the tolerances on the covering job. Not so with these. No seem to be seen!
I ship USPS 1oz first class flat rate without tracking for small orders. Orders exceeding 1oz are shipped first class with tracking. Beyond 1lb is at my discretion. Most likely USPS priority.
The white kind of came out cream colored with these shots due to the lighting in my office. They are a sharp white, however. Same as the xbox one backs I offer.
