"I love it and it fit perfectly"
"Ordered my wedding ring but the size was too large. So easy and quick to change it before the big day. Lost a few kilos in the run up to the wedding and found that the new smaller ring was also now too big. Used the fit for life policy (again, so easy and quick to sort) and now have a perfect fitting wedding ring. nnI chose the tungsten for ‘formal’ occasions, I like the weighty feel, and am going to order a lighter titanium one as an everyday ring for sport/work :)"
"Ordered this for my fiance for our up coming wedding and it fits him perfectly! Super shiny and looks well made. Will definitely buy more from Mens Rings online again."
"I ordered a polished tungsten ring which unfortunately was too big. In the box was a ring sizer so I was simply able to send it back and reorder the correct size. It arrived the same week and it amazing quality."
"Exactly as pictured, very smart looking design"
"Excellent quality very well packaged , quick delivery."
"I am happy to have my MRO ring. Great price, great service, great experience even I though i chose the wrong size. But the MRO team arrange a replacement. Now fits perfectly."
"This ring is exactly as it was advertised and the quality 100% spot on. The returns policy is so easy. The delivery was very quick and I will definitely order again."
Built for a lifetime.
Tungsten carbide is the hardest ring material we stock. Here's why it doesn't scratch, bend, or tarnish — and how ours is made.
Scratch-proof hardness
Tungsten carbide sits just below sapphire on the Mohs scale. 4× harder than titanium, 10× harder than 18k gold — meaning the ring you pick up on day one looks identical on day 10,000.
Heavier than gold
Each ring is pressed from tungsten carbide powder at 2,000°C and precision-CNC'd. The density gives it a real, weighted feel — nothing flimsy, nothing hollow, no plating to wear through.

Not sure of your size?
Tungsten can't be resized — but in a true emergency it can be safely cut off. Best to nail the fit the first time. Three ways to check.
The details.
If you want a ring that looks the same in ten years as it does today, tungsten carbide is hard to beat. The scratch resistance is exceptional — general daily wear, keys in the pocket, knocks on the workbench. This one comes in a 8mm width — It has a satisfying solid weight without being uncomfortably heavy. The polished surface keeps its shine without replating. Note that tungsten can't be resized, so get your measurement right. Good for blokes who want something tough and permanent.
