This chastity device is based on the KTB concept (spikes makes erection painful) but extra security is added by "the cobra" which it makes impossible to remove without the keys.
The spikes keep the ring it in place. They grab on the cock steadly: no twisting and the weight is not supported by the snake rod. It is offered it with 2 different spiked rings for steady grab.
The Kalis Teeth Bracelet (KTB in short) is less known, but a classic chastity device which effectively prevents erection while leaves much of the cock uncovered and the balls free. The spikes are 4-5mm long.
Thickness of the piercing part is 5mm (ca. 4ga).
The spiked ring itself is 36mm (1.4"), 42mm (1,6") in diameter. Choose one!
A simple brass padlock included as well - if it is in stock.
