The details.
Mr Prix is an 8mm tungsten carbide ring with a carbon fiber centerline, built for men who like a sporty, motorsport feel in a wedding band. The dark woven inlay sits between stepped polished edges, so it reads as modern and technical rather than traditional.
Why people choose it
Carbon fiber gives the band texture and depth that a plain metal ring lacks. The tungsten base supplies the strength and scratch resistance, while the inlay works as the accent. It stays comfortable for daily wear with a clean modern look.
Details
- Material: tungsten carbide with a carbon fiber inlay
- Finish: polished stepped edges
- Width: 8mm
- Sizing: 21 sizes, listed in US sizes first
- Tungsten cannot be resized, so check your size first
- Model: Mr Prix (SKU FTR-010)
Who it suits
A natural gift for car and racing fans, and a wedding band for grooms who want something more distinctive than a classic polished ring. The dark center line pairs well with black or carbon-faced watches, and the polished edges keep it smart enough for a wedding suit.
Delivery
Every order is sent with tracking. In-stock orders are usually dispatched within 1–2 business days (Monday to Friday). Delivery time depends on your country. Prices are in US dollars.

Beautiful fitting ring. Superb looking, stylish and smooth.
Quick turnaround, the offer for the ring sizer was a great help. After months of looking in jewellery shops to find these online via add pop up was great.

I purchased a wedding ring and I received it 2 days later which is absolutely amazing considering I live in an area renowned for slow mail delivery. Unfortunately I picked the wrong size and sent it back, and to my surprise I received the new ring 2 days later, plus had email confirmation of when it was shipped etc. all the way through. What truly amazing service, so helpful. I will definitely be recommending Mens Rings Online to all my friends and family. Thank you so much for your excellent service and we both love the ring we chose.

Like many first time customers buying a ring the one I ordered was too big. But thanks to the ring sizer you receive with your order I was able to find what my size actually was. Returning it was a breeze and lightning quick. The ring is nice and honestly looks like it is worth the price or even more expensive. I couldn't fault MRO at all it was a great experience.

Great service and very quick to sort out exchanging of ring sizes. Very happy

2018-04-05
Awesome ring and great customer service, we got my fiancé’s finger sized at a jewelry store unfortunately the sales person got his ring size wrong. And the ring we ended up ordering was too tight. I got to exchange the ring for a larger size and the customer service emailed me to let me know when the rings made it and when the new one would be shipped out. It was express shipping and made it here within a few days. 10/10 will be ordering from here again.
2018-03-12

Oh my word! When I found this ring online I fell in love with it straight away and now that it has arrived it is more beautiful in real life. Thank you so much for providing me with the perfect wedding band for my future husband. He wanted something that was a little different to the usual rings and he loves it just as much as I do!
I must admit I was a little sceptical at first and thought buying online was a but of a risk. A risk I am now so thankful I took!
Thank you MRO!
2016-11-03
We just received our ring that we purchased from MRO.
We wish to thank you for your help and support, the ring is exactly what the description said it would be and the size was perfect.

Mens Rings OnlineThanks for all your help. My husband very happy with his new wedding ring.
2016-08-12
I received my order within 2 days – amazing service provided. I have bought this ring as a 50th birthday present for my partner which isn’t until 27 August so have not been able to give it to him as yet – I have so been tempted but need to resist. I absolutely love the ring and I’m sure he will too. Now we just have to wait and see whether it fits.
I would give your company a 5 star rating.
2016-06-01
Thanks for the excellent customer service, communication and speed of doing things. Recieved the replacement ring today and size etc is perfect. Many businesses don't focus on customer service although they pay lip service to the idea. I will certainly tell others and your products are quality items. Nothing was too troublesome for you. .well done. I will also be back to purchase in the future.
2015-12-01
Hello,
Just want to say I am extremely happy with the purchase. I had to return to resize and this process went seamlessly and I got the ring before my partner's birthday. Quality is superb. My partner is a painter sandblaster and the tungsten ring is still perfect and he wears it every day in the mines. Thanks you so much!!
2015-11-03
The swapped ring fits perfectly. Thank you for the prompt delivery as I got to give to my partner yesterday for his birthday. And he loves it.

The product a 5 of 5, just wanted to say your customer service lady who maintained contact with me, did a fantastic job so extremely helpful! Made the process so easy & updated me with any information I couldn't track down myself. Hard to find such good service these days so I really hope she gets some sort of bonus for going the extra mile.
Will be recommending you on for the great customer service & perfect ring at a great price.
