I love these tags. One thing that is great about them is that the dog's name font is very large and in upper case. Most tags you buy in a store have the name in teeny tiny font which makes it difficult if you are trying to ID a dog who is not keen on a stranger touching him or her. I love that if our kids ever got out (knock knock) their names will be very clear.
I've had my dog's tag for a few months and so far there has been no degredation in visibility of her name either
