Hello! i have a CB6000 for sale. It was worn once for a few hours to test it out. Unfortunately, my testes are below average in size and i continued to *pop* out regardless of which ring was used. Additionally, i am just a bit to thick for comfortable long term wear. So i went with a PA5000 and haven't looked back since! The CB6000 has been in a drawer for a couple of weeks, and i thought perhaps someone on the forum was thinking about buying one - i could save them some money! i'm asking $110 USD. This includes Priority shipping within the USA. Please inquire if outside the US.
