This "Player 1 Player 2" aluminum keychain set is stamped, one letter at a time, on a 3/4" x 1 1/2" aluminum blank and assembled by hand. There are stamps of a classic gaming controller near the phrase on each keychain. The rectangles are made out of Pure 1100 Aluminum, which is food safe and does not tarnish. They contain no Zinc or Magnesium which are often found in common aluminum and can cause skin reactions. This also means it doesn't contain the properties of other metals that might tarnish and/or turn your skin green. Please note that due to the nature of hand stamping, every item varies slightly from the photo. FREE CUSTOMIZATION: Would you like to change the text, add initials, a date or maybe a different design stamp? No problem! Take a look at the last two photos of the listing to see all of our font and design options. Just know we can't fit large 3/8" designs on a smaller 1/4" ring or bracelet. We're always here to help with designs too! Feel free to toss us a message with any questions or ideas you might have. Once your order is shipped you will receive a notification to the e-mail linked to your account, which will include tracking information.
