I bought these slide on dog collar letters to personalize my dog's collar and give the collar a little bling! They are a 1 ¾" tall letters, made of metal and have inset rhinestones.
I wasn't aware when buying this that I would not be able to put these on my dog's existing collar because the collar was overlapped and stitched at both ends. So I had to buy another collar that was made with only a buckle, like a belt. The collar also cannot be wider than 1 ¾"for the letters to slide on. The letters easily slide on, but will slide around on the collar, so I put a little glue on the back of the letter to keep it in place where I wanted it on the collar.
You can personalize your dogs's collar with his name or maybe a cute saying. Since they are easily removed, you could buy more letters and change the look whenever you want.
I did have problems with one of the rhinestones coming loose, but for the price of only $2.99, I would say they are worth the price.
