Super durable. Can read easily after 4 months.
I have 2 Huskies that destroy pretty much everything. Their aluminum rabies tags, bent and chew marks so bad that you can't read it. We didn't expect these tags to last very long. 4 months in, and we can read them, no bite marks, no scratches, no chips... still holding strong. We added their names and my phone number on one dogs, and my wife's number on the other dog. Our dogs have escaped our fenced in backyard 18 times in the past year, and these tags have saved us so many times. We always get a call or text from whomever's found our dogs. The rings that came with were destroyed with days though. Had to add key rings.
