Lenovo Aluminum Bumper Case
Motorola's parent company Lenovo makes some great cases for the Moto Z3 and Moto Z3 Play. Our favorite one is the Lenovo Aluminum Metal Bumper Case.
Yes, this is a slim, thin, yet very strong bumper shell for the Moto Z3 made entirely out of aluminum. Precisely diamond cut, the entire case fits like a glove AND you can use MotoMods with this metal case. It's so slim on the back that it doesn't get in the way.
While the entire case is metal they've rounded the edges so it's soft and comfortable to hold, then added a soft TPU layer on the inside to prevent damage to your phone edges, and to absorb impacts from drops. This is a premium, durable, quality case.
