Make a good thing better with Tantus. The Advanced C Ring is a high quality, heavy duty cock ring with a silky smooth feel that will add an exciting feeling of constriction during use, not to mention a sexy look to your tool! Cock rings may also help you last longer and provide more pleasure during sex and masturbation. Using the ring is simple, just add some water based lube to the inside, and slide the testicles through before the penis. The Advanced ring is sized for the cock ring expert, with a smaller circumference and less 'give' than the beginner and intermediate models. If you're experienced with cock rings, this is the size for you. Once you get comfortable with the feeling, you can move on to the Advanced size for even more pleasure potential. The medical grade platinum silicone material is extremely hygienic; you can boil or bleach your ring for total sterilization, and it's completely odor free and tasteless. Silicone warms to the touch, and retains body heat for a natural feel. Always use a water based lubricant, do not use silicone lube with this or any silicone toy, it can break down the material over time and leave it permanently tacky.
