The ring is 6mm wide (about 1/4"). It is made of aluminum and it's adjustable in size. I have them in two sizes, the S-M will fit sizes 6-9, the L-XL 9-13.
Please write in the "Special instructions to seller" box at checkout what you want stamped on the ring. Unsure if it will fit or not? Feel free to message me with any questions.
The letters are hand stamped one at a time so they might not be perfectly straight or centered which lends itself to the unique handmade look of each ring.
