The design of the collar is simple: it's made of black leather with a D-ring and faux-fur lining to ensure comfort when wearing it. It has that nice and strong leather smell straight from the box. The collar adjusts up to 17" where as the leash runs up to 42". Both the collar and the leash feel rather stiff, but upon frequent use they start to soften up a bit. The craftsmanship of the collar and leash are top-notch. My only complaint is the size/fit of the collar. I have a pretty slim neck; there are only three snap buttons for adjustment. The collar fit me just fine, but I wish there could have been at least one extra snap button so the collar could fit more tightly and firmly around my neck. Overall, I think this collar can fit most neck sizes, and the leash is a perfect length for when you want to walk your human doggy or sub or have him or her tied to a chair or table with the leash. The length of the leash basically allows you to be creative with the many ways you can use it, and the collar is so comfortable that you could wear it all day without it chafing or irritation.
My dom frequently takes me out on public walks with this leash and collar, and at times he restrains me with it when tying the end of the leash to a chair or table. Even though at first I was a bit unsure about the fit of the collar because it felt a tad bit loose on me, I found that after frequent usage I began to like there being some extra room for my neck to breathe. It was also beneficial for when my Dom was tugging and pulling the leash harder; that extra space in the collar prevented me from feeling choked or suffocated by the collar. As an accessory, I thought this collar looked nice. It obviously screams BDSM, but not in an intimidating way. This collar held up well through rough playtime sessions as well as in "vanilla" scenarios.
To take care of the leash and collar, simply wipe it down with a moist cloth when it looks or feels dirty.
My only personal gripe with this collar is that it only comes in black. It would be nice if it also came in white, pink, blue, or purple.
