Love them!
I can’t count how many we have ordered. At least 9. We use them on adjustable clip collars and have only had one fall off after hiking and swimming-which was recovered by a someone and returned to us. This is the only tag our dogs wear and the first thing we order for them. They arrive quickly. The quality is amazing. They are easy to read, strong, and do not wear down (even after 17 years of use).
