3MK Just20g Matt Case

Weighing 20 g with Military Grade certification. Made from durable polycarbonate, it fits comfortably in hand and provides effective protection without heavy armor.

Lightness and excellent protection, finally without bulk

Do you need a heavy armored case to feel truly secure? Just20g Case™ proves you don’t! By creating an ultra-light, frameless case, we broke the long-standing stereotype that effective protection must be heavy, bulky, and unattractive. Lightness and reliability unite in Just20g Case™. Discover how much lighter and more enjoyable it is without restrictive bulk.

The Just20g Case™ is made from durable polycarbonate and comes in two finishes: transparent and matte black. Both versions offer high durability, while the transparent variant—made of pure polycarbonate—stands out with exceptional resistance to yellowing. This material maintains crystal-clear clarity even under intensive use and prolonged UV exposure. With proper care, the case can last the entire lifecycle of your smartphone.

Breaking the bulky Military Grade case image

Weighing just 20 g, the frameless Just20g Case™ passed the rigorous Military Grade test with flying colors. A few years ago, only massive, unattractive armored cases could survive extreme drop tests. Now, Just20g Case™ does it seamlessly. Despite its minimalistic, ultra-light construction, it protects your advanced device, as confirmed by its prestigious Military Grade certification.

Just20g Case™: tailored for your phone and your hand

Custom-made to your smartphone model and… your hand. It fits perfectly like a second skin and delivers an incredible feel while using your phone. The device won’t slip or dig into your hand. You hold it securely and comfortably in any situation. Plus, the case provides easy access to all ports and buttons.
