DUX Wallet and Kickstand Case ($10)
Those looking for something a little different or with more features will want to take a look at this DUX wallet case. It's a standard flip folio cover case, with a look that resembles the iPad Smart Cover.
This case has three different materials for ultimate protection and style. Not to mention a built-in kickstand mode, and a magnetic latch that wakes up your screen. The outside is a soft synthetic leather with a velvet-like microfiber finish on the inside to keep the screen safe.
As an added bonus it can store two credit cards or an ID in the flap when you fold it open. While it may hold more, we wouldn't recommend it as the wallet touches the screen and could scratch your OnePlus 5. It offers plenty of protection, added features, and comes in four different colors for only $9.99
