If you are into old-fashioned technology, you might want to consider getting one of these Typewriter Key Rings. At $72, you have the choice of the letter from A-Z, 0-9, and some other nifty little keys.
Our sterling silver typewriter key rings ($72) are made without using any epoxy or glue. Our keys are attached directly onto the solid sterling ring for a very secure attachment. And all of our keys are, as always, 100% authentic. The best thing about these is they are adjustable! One size fits all!
