3MK SatinArmor Case Sam G998 S21 UltraMilitary Grade

Satin Armor Case

Satin frame that improves grip

Protects what matters

We want to ensure that the control center of your universe is protected as best as we can. Based on the Military Grade standard, we created the Absorber™ test: a series of 26 throws onto steel and concrete. We dropped a phone secured with the Satin Armor Case from a height of 150 cm. The audit of the device after the test confirmed full functionality and no damage to the phone.

Grab and Hold

We’ve heard that in a perfect world, you grab the phone exactly in the middle and always with a dry hand. In real life, it’s… different. Do you know the feeling? That’s why we used a non-slip satin frame in the Satin Armor Case, making the phone sit more securely in your hand, no matter how you hold it.

Camera: Secured

While smartphone manufacturers compete in designing advanced cameras, we take up the challenge and create cases that secure sensitive electronics. The Satin Armor Case has raised edges around the camera, which cushion impacts and protect against scratches.

A dscout research experiment showed that the average user holds their phone in hand for almost 2.5 hours a day. The Satin Armor Case has the certification of the National Institute of Hygiene, ensuring it is free from harmful substances and safe for health – regardless of how much time you spend with your phone.

When protecting phones, we also consider the planet. The Satin Armor Case has passed RoHS certification in an independent laboratory, meaning it is environmentally friendly and complies with strict EU directives on the content of heavy metals and hazardous substances (e.g., lead, mercury, or cadmium).

Recommended for…

The solid black frame looks elegant and modern. It is an interesting complement to the lightweight, transparent back that showcases the smartphone’s design. The thickness of this rigid case is only 1.0 mm – even with the case, you can still comfortably store the phone in your pocket.

Totally Yours

You don’t have to be like everyone else. Show the world what you love or what inspires you! You can easily personalize the Satin Armor Case with a durable print in vibrant colors. You can put whatever you dream up on the case: a graphic, collage, or photo. Yes, it can be your favorite vacation photo!
