"This is my second silicone ring from here and the quality is great. Will definitely get another one in a different colour just to switch it up. Highly recommended."
"Quick delivery, perfect for work"
Built to break safely.
Medical-grade silicone — engineered for the worksite, the gym, the rope-pull, the rock face. Non-conductive. Designed to release under tension before your finger does.
Almost weightless
You'll forget you're wearing it. Made from medical-grade flexible silicone that conforms to your finger and stays comfortable for 12-hour shifts.
Ring-avulsion safe
Engineered to tear at roughly 25kg of pull-force — well below what it takes to degglove a finger. Tradies, electricians, climbers, lifters: this is the ring you wear when the metal one comes off. Non-conductive, too.
Days warranty
Silicone doesn't last a lifetime and we won't pretend it does. 30-day replacement warranty on tears, splits, or manufacturing defects. After that, swap it for a fresh one — they're built to be replaceable.

Not sure of your size?
Silicone is flexible — but the right size makes a real difference for comfort. Three ways to check before you order.
The details.
The Hollow Square Dark Grey silicone ring features a squared profile and hollow construction in a muted, versatile dark grey. Made from medical-grade silicone, it is sweat-resistant, waterproof, and non-conductive, safe for any work or sport environment. The angular exterior gives a rugged, industrial aesthetic while hollow channels reduce weight without compromising the ring's presence. Silicone rings break away under extreme pressure, protecting against ring avulsion injuries. A practical, masculine choice for active men who want a ring that stands out from the crowd.
