Stamped with " always under the same sky" following by the natural designs. It is a great gift for long distance couples, military wife/husband/boyfriend/girlfriend, long distance friendships, army dad/mom/brother/sister ect. Copper tags will tarnish and develop a patina over time. This is a natural process and adds to the uniqueness and charm of the tag. Buffing with a superfine steel wool or a jeweler's cloth can bring back the shine. Please note I could only stamp one side.

They are handstamped jewelries but not engraved or manufactured item that is why each piece is a unique one of a kind treasure. Aluminum and stainless steel are a perfect alternative to the more costly sterling with all the hypoallergenic properties you demand. Aluminum and stainless steel will not rust, tarnish, and is very wear resistant. All of my stamped jewelry is hand stamped. This being said it is custom made for you with care and quality in mind. With each letter being stamped into the metal individually there will be variation between depth, spacing, and alignment. Each piece will be a unique one of a kind treasure.
