How do I find my ring size for the Black and White 8mm Silicone Ring?

We recommend using a ring sizer tool for the most accurate fit. You can also use a piece of string or strip of paper to measure your finger circumference, then divide by pi (3.14) to get your diameter in millimetres. Our ring size guide on the website shows how this converts to Australian and international sizes. If you're unsure, our team is happy to help — just contact us before ordering.

Can I wear a silicone ring at work or at the gym?

Silicone rings are specifically designed for active wear. They are flexible, non-conductive, and safe for environments where metal rings can be hazardous — including electrical work, heavy machinery, and gym training. If the ring gets caught on something, it will stretch or break away rather than injuring your finger. They are also waterproof and easy to clean.

What is your exchange policy if my ring does not fit?

We offer easy ring exchanges if the size is not right. Simply contact our team within 30 days of receiving your order and we will arrange a swap to the correct size. For custom-made or engraved rings, exchanges may be limited, so we strongly recommend confirming your size before ordering. Our ring sizer tool is available for free with any ring purchase.

How quickly will my ring be dispatched?

In-stock rings are typically dispatched within 1–2 business days. Custom and made-to-order rings may take additional time depending on specifications — we will provide an estimated timeframe at checkout. We ship Australia-wide with tracking, so you can follow your order from our door to yours.

"This ring is really cool. I like the design as it really stands out. I’ve had a lot of compliments. It fits nice and snug and doesn’t move around"

— Letisha R.

Built to break safely.

Medical-grade silicone — engineered for the worksite, the gym, the rope-pull, the rock face. 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.

100%

Safety-rated

Designed to tear at ~25kg of pull-force — well below what's required to degglove a finger. Tradies, electricians, climbers, lifters: this is the ring you wear when the metal one comes off.

The details.

Silicone rings have become the practical choice for active blokes. This one is made from durable medical-grade silicone — it stretches, flexes, won't conduct electricity, and if it gets caught, it's designed to give before your hand does. This one comes in a 8mm width — Low-profile fit means it doesn't catch on gloves or gear. Waterproof, easy to clean, and comfortable enough to forget you're wearing it. If you work with your hands, do heavy lifting, or spend time outdoors, this is worth having on your finger instead of anything valuable.
