Each Aneros Progasm Ice is a unique piece. The production process creates a distinctive air bubble, making every unit one of a kind. Its sleek design ensures an intense prostate massage, supported by the patented hands-free design. Despite its appearance, the Ice is not made of glass. Instead, it is crafted from an award-winning, FDA-approved, medical-grade, and food-safe plastic that is increasingly used as a substitute for glass because it does not break. Additionally, the production of this plastic releases fewer gases compared to other types, making the manufacturing process more environmentally friendly. It is the largest Aneros model with a rounded perineum tab design. The Kundalini 'K-Tab' offers additional sensations. Suitable for advanced and experienced users.
