Looking for a thin Samsung Galaxy S20 Ultra case? There is no thinner case than the MNML case, which comes in at just 0.35 mm. It’s so thin, it will look and feel like you have no case at all. It doesn’t offer much drop protection, but it will protect you from the day-to-day scratches that can accumulate. The MNML Case comes in three different colors, including frosted black, frosted white, and matte black.


Poetic Karbon Shield

The Poetic Karbon Shield is a simple, black TPU case that doesn’t skimp on protection. It’s not as durable or bulky as some other Poetic cases, but with a lip around the camera and screen and precise cutouts, you can feel confident in the face of drops. The back panel also has carbon fiber texturing that provides some extra grip. Even better, the Poetic Karbon Shield is compatible with most screen protectors.


Spigen Liquid Air Armor

A patterned back with an anti-slip matte finish helps with the grip and it utilizes air cushion technology for impact resistance. A slightly raised lip keeps the display and rear camera safe as well.


Caseology Parallax

Speck Presidio Grip

UAG Plasma
