This is a cock ring. Cock rings are designed to limit the flow of blood to and from the penis to promote stamina and more intense orgasms in men. A cock ring can also make a penis harder or feel bigger, but it isn't going to be the case for everyone.

Cock rings can only be worn for a maximum of 30 minutes at a time. An hour break in between uses is required to prevent damage to the penis.

This ring is metal which means that you should really know your size before purchasing. If it is too small, it can become stuck, and need to be removed by a doctor.

This cock ring is made from stainless steel. The black band may be a different material or painted. It is impossible to tell, and I cannot locate any information about it. The band has no defects, seams, or rough spots which makes it extremely comfortable (so I am told).

Steel can be cooled or warmed in water 15 minutes before use. We recommend warming this, but others may enjoy cooling sensations.

This is completely rigid and unforgiving, so make sure you have an accurate measurement of where this is going, so it doesn't get stuck.

This is about a half an inch wide. This makes it reasonably sized to me. It is on the thicker side for what we normally use, but it doesn't get in the way at all. The 2" diameter translates to a 6" circumference. This fits my boyfriend perfectly around his shaft and testicles.

This reminds me a lot of a men's wedding band with the domed exterior and the black band. It is very stylish and classy.

Every part of this is smoothed down and comfortable.

This can be cleaned with toy cleaner or antibacterial soap and warm water. You can also sanitize it by boiling it, wiping it with 10% bleach solution, or putting it in the top rack of the dish washer. Dry it well and store it however you like.

This is compatible with all types of lubricants.

The packaging was nice. The majority of it is the black drawstring bag to keep it in. The rest was a tag on a chain. The tag doesn't have a lot of information on it. Just has the company, name of the product and its size, and the information about not wearing for more than 30 minutes without a 60 minute break.
