Hand stamped, one character at a time, our Secret Message cuffs start out as 1/4" x 6" cuff blanks, then hand formed with a hammered finish with your stamping request on the inside, where only you can see it ;) We have four choices for metals: aluminum (will not tarnish), brass, copper, and sterling silver.
We can stamp about 40 characters including spaces on the inside, and we can optionally stamp two symbols on the outside ends, just message us for symbol requests
