3MK Just20g Matt Case Samsung Galaxy S25 Ultra

Lightness and perfect protection finally without armor

Do you really need to put a heavy armor on your phone to feel truly safe? The Just20g Case™ proves that you don't! By creating an ultra-lightweight, frameless case, we have broken the long-standing stereotype that effective protection must be armored - meaning heavy, clunky, and unattractive. Lightness and reliability have found a common language in the Just20g Case™. Discover how much lighter and more enjoyable it is without the burdensome armor.

The Just20g Case™ is made of durable polycarbonate and is available in two variants: transparent and black matte. Both versions are highly durable, while the transparent variant - due to the use of pure polycarbonate - stands out with exceptional resistance to yellowing. This material provides crystal clear transparency that does not fade even with intensive use and prolonged exposure to UV radiation. With proper care, the case can serve throughout the entire life cycle of the smartphone.

Breaking the image of a clunky Military Grade case

Weighing only 20 grams, the frameless Just20g Case™ has passed the rigorous Military Grade test with flying colors. A few years ago, extreme drop tests could only be survived by bulky, ugly armored cases. Now, Just20g Case™ has done it without any ceremony. Despite its extremely lightweight and minimalist design, the case perfectly protects your advanced equipment, as confirmed by the prestigious Military Grade certification.

Just20g Case™ is a custom-made case

for your smartphone model and... your hand. It fits perfectly like a second skin and guarantees an amazing experience while using the phone. The smartphone does not slip or dig into your body.
