The CoverON FlexGuard series slim case for the Asus Zenfone 3 Zoom is made of flexible TPU (thermoplastic polyurethane). Simple, clean, and stylish look. Don't get bogged down with a heavy case; the FlexGuard weighs less than 1 ounce and is only a few millimeters thick. It's very easy to slide in and out of your pocket, yet has a very subtle tackiness to improve your grip. The FlexGuard also has the attention to details down. A lightly dotted interior is designed for slightly better shock absorption. A must-have minimalist case for the Zenfone 3 Zoom - brought to you by CoverON.
