I never understand why almost all phone cases are so thick, bulky and heavy. Totally unnecessary, and insanely expensive in local stores. I can only take something like this from Dollartree:
Notice that it is called "cell phone bumper", so I searched it on Amazon for my Nexus 6 and found two:
LJSGK Protective Aluminum Alloy Bumper Frame Case
Slim Armor Border Shockproof Bumper Frame Case Cover
I wish I bought one of these. I'm going to drill some more big wholes on the one I bough to make it cooler and lighter:
So sad, cannot find one for LG Volt
Thanking to sam888, ordered two of these on ebay:
[update 01/30/16] Received above cases from China and extremely happy! Super thin, 0.8mm, and light, 0.5 oz, and protects fully the phone. In comparison, the Spigen crap is 1.3mm thick and 1 oz heavy, and still leaves the up and down sides of the phone unprotected.
