Amazing Product!

Love this style. I highly recommend! Also, very friendly customer service.

Excellent, ordered a second

Good quality, better then expected. I bought 2 all. Carbon rings. Fit as expected.

quality of workmanship

ring was beautiful. resembled a matte metal! my fault, had to exchange for 1/2 size bigger:)

Great product, service and communication

I love my new ring, it came faster than originally told. They were very easy to deal with. Highly recommended!

So nice but totally doesn’t look like the picture

The ring arrived in a timely fashion and the process was super easy and dealing with the manufacturers was awesome. BUT in the picture the ring looks like a solid black band with no detail. Unfortunately the ring arrived and it has a ton of detail and is nothing like the advertised picture. It was very disappointing as my husband wanted his wedding ring to look like the picture. Solid black. He says it’s nice and not at all what he wanted but it’ll “ grow on him”. Yikes. It’s too close to the wedding to return it. Other than that a very cool product. Light as a feather too!

This is a great ring

So I ordered this as a guy that's into all things carbon fiber, I wanted a full CF ring not just an inlay. The ring was shipped sooner than the 3 weeks in the description and came in a box and packaging that kept it protected. It looks truly amazing and is very very light. I will be ordering one of the different styles soon. Great product!

Amazed!!

I'm beyond impressed with this ring! My fiancé got it for me for our wedding and I love everything about it! From the matte finish to the untra light weight, it's truly impressive! The unidirectional carbon fiber weave looks amazing in the lighting! I'm so happy with it! Thank u!!

Wedding Rings

Excellent shipping time. Fantastic feel and weight. I cannot wait until the wedding day of March 5th to start wearing them. It beats the qalo silicon rings that I was tempted to buy.

Quick shipping on a custom

Quick shipping on a custom ring for my husband. He loves it! It's so lightweight and durable and it's manly rather than gold and diamonds and flashy **** that other men wear
