Excellent, Excellent, Excellent! I have a pack of dogs and they play so rough with one another that they often times lose their tags. In the past they have bent their tags. These are durable and extremely easy to read. I loved the engraving offered! I was able to write medical conditions that others would need to be aware of if they happened to come across my pet, like blindness or hearing impaired. Very pleased with the price too and they came with jump rings! I will be back for future purchases!!!
