This mens carbon fiber promise ring pairs a matte-black forged carbon shell with a cocobolo wood interior. Cocobolo is a dense Mexican hardwood that shifts between orange, red-brown, and near-black within a single length of timber.
It reads dark outside and carries warm color against the skin. Suited to men who want something beyond plain metal, less so to anyone after a bright band. The carbon fiber keeps it light on the hand, and each piece is handmade with engraving available.

These bands are built from materials made for daily wear: forged carbon fiber, titanium, and black ceramic, usually with a wood, stone, or metal inlay. They resist scratches and water far better than soft gold or silver and keep their finish over years of use.
Titanium and ceramic are hypoallergenic and sit well against sensitive skin. Every ring has a rounded comfort-fit interior for easy on and off and smooth all-day wear.
Each ring is made to order at your exact size, so it is not resized afterward. If your size changes, we remake or exchange the ring rather than stretch or cut the band. Free engraving is included on most rings, set inside the band at no extra cost.
Can this ring be resized?
No. Every ring is made to order at your exact size, and these materials cannot be reshaped like gold. If your size changes later, we remake or exchange the ring rather than resize it.
Is this ring hypoallergenic?
Yes. Our carbon fiber, titanium, and black ceramic bands are hypoallergenic and nickel free, with no plating to wear off, so they suit sensitive skin.
Does the ring include engraving?
Free inside engraving is available on most bands at no extra cost. Add your engraving when you order, and note that engraved rings are made to order for you.
How long does it take to make and ship?
Each ring is handmade to order, usually in 5 to 7 business days, then shipped worldwide with tracking. The price you see is final, with no surprise import fees.
How do I find my ring size?
Measure carefully before you order, since these bands are not resized. Our guide to finding your ring size at home walks you through four easy ways.
How do I care for the ring?
Wipe it clean with mild soap and water and dry it. Carbon fiber, titanium, and ceramic shrug off water and sweat. For a wood inlay, avoid long soaks and harsh chemicals to keep the grain looking its best.
