The DURO® Ring Master adds a built-in stand to genuine Arclin™ Kevlar® protection. A magnetic 360° rotating ring works as both a kickstand and a grip, so you can prop up your iPhone 18 or hold it one-handed — backed by MIL-STD-810H drop protection and MagSafe.

DURO® Ring Master Case
Ring Master takes the same genuine Arclin™ Kevlar® protection as the rest of the DURO® line and builds a stand right into the back. One magnetic ring works as a kickstand and a grip, so you're not carrying a separate pop socket or folio just to prop your phone up.

One Ring, Two Jobs
The ring sits flush against the case until you need it. Flip it out and it holds your phone upright for video calls or watching something hands-free. Loop a finger through it instead and it turns into a grip that makes the phone a lot harder to drop in the first place.

Genuine Kevlar® fiber
The case is built from 600D Arclin™ Kevlar® fiber layered with PC and TPU — tougher than the fiber alone, which is what lets it carry a moving hinge and still take a drop. It's the same aramid used in body armor, just engineered here to hold its shape under the extra stress a ring stand puts on a case.

Precision-Fit for the iPhone 18
Every cutout — camera bump, buttons, charging port, speaker grilles — is mapped to the iPhone 18 Pro and Pro Max. The raised lip around the camera keeps the lenses off any surface you rest the phone on, ring folded in or not.

MagSafe Built Into the Ring
The same magnet that anchors the ring also handles MagSafe, so chargers and mounts snap on with a solid click instead of a loose wobble. Wireless charging still passes straight through — you don't need to fold the ring out of the way first.

【 MIL-STD-810H Certified 】
MIL-STD-810H is the U.S. military's standard for testing equipment against real-world drops, vibration, and shock — not a number picked for a product page.
DURO® Ring Master is certified to it, so the extra protection from the reinforced shell is backed by an actual test standard, not just how sturdy the case looks.

Skip the Extra Accessories
A case, a stand, and a grip usually mean three separate purchases stacked on your phone. Ring Master folds all three into one shell, so there's nothing extra to lose, forget to pack, or peel off before it does its job.
