Despite its appearance, the Progasm Ice is not made of glass. Rather, it is made of an award-winning, FDA approved, medical and food grade plastic which is rapidly being used as a replacement for glass because it does not break. The production of this plastic also emits less gases than other types, making the manufacturing process better for the environment. Each Aneros Progasm Ice is a one-of-a-kind. The production process creates a unique air bubble, making each one unlike any other. The sleek design provides an intense prostate massage backed by our patented hands-free design. Just like the original Progasm, this famous prostate stimulator has an overwhelming reputation for being the best P-Spot massagers ever invented. They were scientifically developed to massage the prostate gland and the perineum, which greatly enhances sensitivity and sexual function. Ergonomically designed to improve/ induce orgasms for men. Progasm has the most girth to its design and is considered the most advanced design in the evolution of male g-spot stimulators.
