The Bound by Diamonds open ring gag is a an attractive way to restrain someone or yourself from speaking and closing their mouth. Unlike many other gags, this product features a ring that keeps the mouth open and allows breath. It also has three different sizes of rings allowing customization in how wide the mouth is opened.

Depending on its size, you are able to insert a penis or dildo through the ring for bondage oral sex play. The large ring will accommodate up to a 2' diameter. I tried it out and was able to get the Blue Rider through the large ring without a problem.

The ring is worn behind the teeth, and is comfortable even when being bitten down on. The only potential problem is finding a comfortable spot for the tongue while wearing it.

Because of the customizations and comfort while wearing it, I would recommend it for beginners, but I feel that advanced users would still have fun with it.

I will start by saying the gag doesn't remotely fit me. I have a small head (small body, small head) and I don't have enough hair to make the gag fit better. I have gotten used to lingerie not fitting, but I did not expect this from a gag! I am disappointed.

According to the box, the gag is adjustable and is one size fits most, so I will assume I am an odd size. The closure is a double D ring that can be tightened to approximately 20 inches around. The gag can fit up to 26 inches around the head.

The reason why I could not get the gag to fit me is because of the 'diamond' design. The crystals, which are securely sewed onto the strap take up eight inches of the strap that could be used for tightening. If you pull the strap so tight that it reaches the 'diamonds' it will not tighten any further. If the gag had been made with a few less 'diamonds' it would have fit me.

I will be using a seam ripper to remove the 'diamonds' and will update in a follow up review.

The best feature of the product is the interchangeable rings. This gag forces your mouth open, and it thankfully comes with three different sizes for those of us with different sized mouths. The small is 1.75", the medium is 2" and the large is 2.25". The rings are super easy to replace, simply clip them in and go. They are made out of Phthalate- Free PVC and can be sanitized between use.

The strap has a wet leather look to it, but it is primarily PVC and polyester. It looks great and is quite sturdy.

I could not use the gag, so I apologize, but until I alter the gag to fit me, the performance part of my review will be lacking.

Ignoring the fact that it didn't fit, the gag was easy to put on, and easy to remove. It is fairly comfortable when worn, as long as you don't mind holding your mouth open.

This was my first gag, so I was really disappointed when it did not fit. It looks really great, and I enjoyed holding it on my head, pretending to wear it. My partner and I were looking forward to using it, but instead it has sat in a box waiting for me to have time to rip the seams on the decorations. I don't want to alter it because the faux diamonds are one of the best features about it, and it kills me to pull them off. Eventually I will do it, because honestly, other than a pretty belt I have no use for it.
