I really like the c rings they're made really well and last forever. I've got 4 of them now and I love the look of my balls stretched nice and tight while my cock is so hard.
I'd recommend them to anyone who is thinking about getting any type of rings
Perfect fit - no slippage - no pinching.
Travelling through all airports now, metal detectors "go off" when I wear my metal cockrings. I refuse to take off my metal body jewellery so have to explain every time that I am wearing body jewellery. However, to get around this very annoying situation, these wonderful silicone rings work perfectly. They fit well, very pliable, and whats more, the metail detectors at airports to not beep when one passes through them. The 40 cm is THE perfect fit. No slippage and no pinching. Even when wearing more than one, they do not irritate the skin and they can be worn "for ever." A reminder though, take them off and wash them on a daily basis to keep skin and C-ring healthy.
