This gorgeous metal and leather collar has flat round rivets embedded in the leather in vertical pairs. Two pairs sit at the outset, one pair on each side. Two pairs sit together in the middle, with a very sturdy D ring situated in the middle. The D-ring is sandwiched using these rivets between the inner 1 and 1/2" band and the thinner outermost 1/2" band. My partner and I tried SO incredibly hard to rip the D-ring out, but no luck, to our satisfaction! It seems that no matter how hard we tug and pull on this collar whether with our hands or with a leash, this baby is not gonna let you go. The D-ring is also a very appropriate size; I can't see any leash or nipple clamps not being able to clasp onto it.
The thinner, but still impressively sturdy, band also houses the metal buckle. There are ten succinct sizes (little holes that the buckle can connect through).
This collar is 20" long, and curls in on itself to accommodate virtually every neck size. The smallest size has about a 6" diameter, which is pretty small, but I know that some petite girls (myself included) may find it a little too loose. It didn't seem to interfere with any of the collar's functions or comfort, though, so I'm not complaining. I always had a lot of tail hanging off because I had to tighten the collar so much, but it never seemed to flap around or get annoying or distracting or in the way or any of that. Again, no complaints here!
The width is 1 and 1/2" (tall; the width of the actual leather band, holding it between your fingers is about 1/6" thick), and considering I was contemplating buying this and a 2" collar, I'm really glad I stuck with this one. I think 2" would have made my neck feel a little TOO stiff and constrained. I have enough range to move my head around, but when my partner wants get me into a certain position, this collar can still get me there. This collar isn't flimsy in the least, especially when you have two or three layers of this thick supple leather wrapped around your neck! It will stay in place, and when it gets pulled on, it WILL let you know. This collar is in charge of you, not the other way around! As they say, this thing wears YOU.
This doesn't itch the bottom of my chin or any part of my neck. No chafing, no itching, no raw skin in sight. It's just so soft! Surprisingly so. Some collars have fur or unfinished insides. Fur I find a little tacky, and unfinished leather is a scratchy gross pain to deal with, especially if you sweat on it. This leather is some of the highest quality I've ever had in my BDSM kit. It's smooth to the touch and glides across your skin with no drag, just ever so slight nerve-tingling pleasure.
There's no locking ability on this collar, which I know can be a con to some, but it personally didn't bother me.
I've dealt with a lot of leather, and leather of this caliber tends to crease down (in the good way!) into a smooth, silky and strong material, so don't worry about the longevity of this product. It will definitely last you a long time. The dye is really top notch as well, so no worries about bleeding colours if you sweat. This baby smells sweet and musky like good leather should, but doesn't reek its scent all over your living room.
