Amazing!

I’ve tried so many rings over the years and none were like this. This ring is so comfortable to wear, feels good, and does what it’s supposed to. Also, the width is excellent - many are so wide and bulky. You’ll love it!

A must have for guys with bigger balls

i bought this for fun in the bed room. It has turned out to be the best thing for every day wear in the heat. We have had some warm days lately and this ring is a must have wear it under short pants swim wear anything keeps my balls from sticking to my legs and always having to adjust my self. It looks great feels amazing on I have tried many. To say the least this is my go to and only ring i will wear other than a wedding ring. The customer service is amazing and very helpful. I will buy more I like the fact it is then when you have larger balls you do not always want a big thick ring So I will be looking at all they have to offer from this point on i might just get in the 2nd color to mix up my look as it is my everyday wear item. Much thanks.

Good product and service

I received my primal ring and noted that it was well packaged, made very well, sleek design, and had good customer service through the whole experience. However, I don’t think I would have ordered the size I did. I was in between sizes and order the one below based on reviews and correspondence with their support team. Still, I don’t think this ring fits properly and probably could have used a size smaller, unless it is supposed to be snug (while erect) and not tighter.

Adding to my collection

I have 5 of the diffent styles and sizes now and I love them all. I have also bought one for a friend as he loved my one and wanted one for his birthday. The silicone rings give you a great feeling and with a bit of give in them if you are between sizes, I was between 40 and 45 and went for the 40 in silicone which feels amazing. The steel rings are great too and giving you that really firm, confident and secure feeling.

How to measure for the perfect fit

Gather Your Supplies. You'll need a piece of string and a ruler to get your measurement. We recommend using a string instead of trying to use a soft tape measure.

Measure. Wrap the string around your penis and behind your balls. Mark the string where it meets. You want the string quite snug. You should be able to just fit a finger between your skin and the string when you're soft. And it should be comfortably tight when you're hard so that you can't fit in a finger. You may want to measure both soft and hard to double-check your size.

Determine Your Size. Measure the distance from the end of the string to the mark.  This is the circumference.  Use the handy table below to get your size.

Circumference Ring Diameter
13.0-14.5cm (5.0-5.75in) 40mm (~1.6in)
14.5-16.5cm (5.75-6.25in) 45mm (~1.8in)
16.5-18.0cm (6.25-7.0in) 50mm (~2.0in)
18.0-19.5cm (7.0-7.75in) 55mm (~2.2in)

Tips For Measuring

  • Most guys are in the 40mm-50mm range.
  • 55mm is a pretty big ring. So if you're not bigger than average, try measuring again and make sure you pull the string tight.
  • If you have a good-fitting round ring, MEASURE ANYWAY. You may find your Primal ring size is 5mm (~.2 in) smaller than your round ring size. Our keyhole shape fits a bit looser than a round ring with the same diameter.
  • Measure twice!  Due to the intimate nature of these rings, we can't accept returns or exchanges.
Remember: Safety first! Do not wear a ring that is too tight, and remove the ring immediately if you feel discomfort, a sensation of coolness, observe any changes in color, bleeding, or feel tingling or numbness. If in doubt, take it off. Men with pre-existing genital conditions or injuries, or those taking anticoagulants should consult their physician prior to use. Cock rings should not be worn for more than 30 minutes, and you should not sleep in a ring.
