FINON Flexible Clear Bumper Case ($9)
The FINON Flexible Clear Bumper case for the OnePlus 6T is a solid all-around case.
They're using a soft and flexible clear TPU material to keep your phone safe. It's also really thin. Then, they've color-matched the edges and the top/bottom in black, blue, or a few other colors. We really liked the blue, especially when paired with the blue OnePlus 6T wallpaper.
Colors aside, this case is soft, flexible, durable, and has precise cutouts for everything you'll need. They raised the edges around the screen and camera lenses too.
