THICK Hand Stamped Pet Tag These tags are THICK & sturdy. They are soldered closed on a jump ring then attached to a key ring. They are 1 1/8 in diameter which is just a little bit bigger than a quarter size. They are also 1/8 of an inch thick. So you won’t see the stamping on the other side. You can choose either Aluminum or Copper for the material. Pick up to 2 phone numbers & choose font. If you’d like anything else personalized please message me FIRST before placing an order. THANK YOU! :) Handmade Mountain & Trees Dog Tag, Cat Tag, Lover Pet Tag
