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 semi-erect cock, the ring regulates the amount of blood that leaves the penis, thereby keeping your erection longer. You and your partner can achieve great satisfaction, with longer lasting intercourse. The cock ring is easy to put on because it uses a belt buckle system. There are 8 notches on the loop. This cock ring can accommodate penises up to 8\" in circumference. It measures 8.5\" in length and .5\" in width.
