MaxBoost mSnap Perfect Fit Case ($10)
Those looking to add a case for protection without any bulk will want to consider this case from Maxboost. It is one of the thinnest cases we've seen, looks good, and is wallet friendly.
This case offers 360-degree protection and is made entirely out of an extremely thin and durable polycarbonate plastic. It snaps into place thanks to small slits in the corners that allows for just enough flex for users to install it. Additionally, those corners help disperse force in case the phone is dropped.
If you're looking for an extremely thin case this is it.
