This collar is so cute. I love how the letters look and the feel of the silicone. This collar is made from high-quality silicone, and it is easy to clean. The print of the letters is nice and crisp. The only issue with the collar is getting the metal nub into the hole. I was struggling at first, but I found it goes in a lot easier if you stretch the silicone around the hole as you insert the metal nub. It’s a little difficult to get it in, but stretching it out helps get the metal nub in the hole.
