Purchased two tags for each of my med/large dogs. We hated the jingling of old tags and were paying for ones that rivete onto the tags but had to replace those with the collars. Now I can reuse the tags whenever I need new collars! Tags are sturdy and attached very easily. They do not appear to be able to slip or be pulled off easily. Etching could have been deeper as it can be difficult to read at an angle, but still a nice product!
