A great unique tag for your four legged friend! These tags come in aluminum, brass, or copper. Personalize them with your pet's name, phone number, address, and whatever you like on the fourth side! PLEASE LET ME KNOW: 1. Name (up to 8 letters) 2. Phone Number 3. Address (up to 14 characters, counting spaces) 4. What you would like on the 4th side (up to 10 characters with letters, or up to 5 symbols)- See last picture for symbol stamps Bars are made of either pure aluminum, brass, or copper. They measure 1/4" x 1 1/4" long. **Please note that these items are hand stamped meaning that I stamp each letter one at a time. So please do not expect the letters to be perfectly straight or centered. The process is very different from traditional engraving, which carves a light groove into the metal. Stamping is a more forceful technique, where each individual letter, number and symbol is stamped by hand, one at a time with a hammer and steel stamp. This is much deeper than engraving and therefore, there will probably be a slight impression on the other side.
