Air Airflow Cock Ring Oxballs Silicone/TPR Blend Cool Ice. At Oxballs, we love wearing cock rings and ball stretchers. Whether it is under our clothes on the go or for some hot and heavy hole stuffing something just feels so damn good about plumping up your cock and pushing your nuts out. That being said, there are days when we want that beefier, bigger bulge but without all the bulk on our boys, that is where Ox got the idea to make our new super lightweight cock ring, AIR. AIR is a super sleek and aerodynamic cock ring designed to beef up your meat while feeling like you have got on nothing at all. Stats approximate width 2.5 inches, height 1.10 inches. Outside circumference 8 inches. Inside circumference 4.5 inches. Inside diameter 1.45 inches. Weight 2 ounces. Water based personal lube is the best lubricant to use with the Air Airflow Cock Ring.
