Moving to the charging case we observe something completely different as if it was designed entirely by a different company.

I pried the inner lining very carefully as I didn't know the position of the battery. The back of the case on the hinge side has solid plastic protecting the battery so you can safely pry on that side and completely remove the entire "functional" part of the case from its outer shell very easily.

I accidentally broke the hinge but it's not that fragile. It's just that at this point having already disassembled them, I knew I was not going to be able to use it ever again. I continued basically for the purpose of sharing the experience with others.
