For the well-endowed penis, the Man Cage Medium measures 4 inches in length and is curved for comfortable, discreet wear and no-boner-zone assurance. Alter the size for the best fit using the included accessories and enjoy hypoallergenic chastity fun. With (almost) everything you need to get started straight away, tailor the fit using the included U-rings, spacers and pins and keep pesky peens in check. Ventilation holes ensure the wearer remains comfortable throughout wear, and a hole in the tip means they can urinate and ejaculate without removing the device. The only thing that's missing is lube! Pick up a good quality water or silicone based one to ensure maximum comfort. As with all male chastity devices, always remove before sleeping.
