Oxballs Air Airflow Cockring - Cool IceAIR is a cockring with an entirely new look and feel, a larger size ring that's as light as hot air. It's made of our firmer, super stretch PLUS+SILICONE TPR silicone blend; it has the rubbery stretch of silicone but the strength of TPR. This is a bulge enhancing cockring it pushes everything up and out but doesn't grip too tightly, dig or pinch.
