www.dhgate.com/product/adult-sex-toy-male-chastity-device-penis/194926003.html I have been wearing this without the basering for 30 days as the cage opens like a book and has places to wrap an o-ring around the device and the glans to work like a prince albert. I also made inserts using instamorph to make it tight enough to be impossible to pee or ejaculate if hard in the cage, but fine when flacid. Just do not try using a vibrator wearing this as for some reason it will leave your member a bloody mess. Great comfy cage so far.
