I gently removed the key from a 1930-40's era typewriter. The key was polished and secured to an oak leaf ring - it measures 13x7mm and has oak leaf details on the sides. This particular ring was made with the letter A but I have all of the letters available.
Will be shipped in a jewelry box, appropriate for gift giving.
If you need more rings, we can create them for any letter - just let us know!
