From Him:
You might be surprised to find out, these rings can be put towards a myriad of applications. The most simple and obvious of these, at least to me, was the act of putting ones cock inside of them. With the three different sizes you'll get in this one package, you're able to place them at different points, and find the way in which each one can be put to work for you. Caution is advised, however, as these guys are hard metal, and you're not going to be able to flex out of them should the need arise. Consider them unyielding to almost anything, which could certainly be considered a good thing if that's what your situation calls for. They make for some of the best standard and versatile cock jewelry that doesn't require piercing that I've encountered or used.

Other, more surprising applications include their use in a harness, such as the one She and I reviewed here:

Bare As You Dare Harness

Because of the different sizes, you're able to swap out the O-Ring quickly and easily, as your dildo needs fluctuate, for optimal security.

The added golden sheen to the metal also provides a nice touch, as it'll make the rings pop when you're surrounded by a sea of chrome that is usually standard when it comes to metal implements and accents. Clean up is also simple, a little soap and water and it's good as new, you can even throw it in the dishwasher for an added bonus. There's not too much you can do to damage this implement, short of taking a hammer to it, and even then you're going to have to work up some ire. And if you do, just get a new set, they're cheap to boot!

These guys still serve us very well, and we're happy to have them! The finish has gotten a little rough, though
