These are beautiful, sturdy collars. I bought a small and medium for two dogs. Love the colors, the peacock and teal jade, that I bought. They are strong and padded all around. The padded feature was what drew me to the collars-less rubbing on the dog's necks. The diamond pattern is beautiful-very royal looking. It has reflectors that surround the diamond pattern. While I haven't seen this feature lit up yet as my dogs don't go outside in dark much, it's still a great thing to have especially when the days become shorter. Very pleased overall.
