This high quality leather cock ring will make sure your cock stays harder for a longer period of time. While looking good at the same time, after you wrap it around your sem-erect cook, the ring regulates the amount of blood that leaves the penis, thereby keeping your erection longer. The cock ring is easy to put on because it uses a belt buckle system. There are 8 notices on the loop. Adjustable up to 8 inches in circumference, 0.5 inches in width.
