This is the best collar we own. The inside fur is very plush, rolls over the top and under the bottom for extreme comfort, and augments the snug feel. This collar is rigid enough for serious play yet secures the neck so softly. What an exciting feeling! The strap and locking buckle function exceptionally well-they are not cumbersome and very adjustable. The construction quality is outstanding. This is a luxury item that has shown little wear after 30 months of dedicated use. We will soon purchase the matching fur-lined wrist and ankle cuffs as our six-year-old leather cuffs from another source are wearing out. Writing this has made me eager. I need to go have fun now.
