DBrand Grip Case $30
Dbrand is a company that almost everyone on the internet should be very familiar with. They're a popular brand that offers tough skins for almost everything you can think of. You can get a Dbrand "skin" for your Xbox, Nintendo Switch, Drone, Macbook, Galaxy Note 10 or of course, the OnePlus 7 Pro.
However, Dbrand also makes cases for select smartphones, and the Dbrand Grip for the OnePlus 7 Pro is actually a pretty great case. You can get this rugged and insanely grippy case in a few different styles, and you'll love it.
DBrand uses an advanced shock-absorbing TPU polymer material that's not only thin, lightweight and tough, but extremely grippy and textured. It'll almost stick to a wall, which is crazy. If you know anything about Dbrand, it's that they love to protect smartphones. Give it a try.
