Every Aneros Progasm Ice is a one-of-a-kind. The production process creates a unique air bubble, making each one unlike any other. Despite its appearance, the 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 is unbreakable. The Progasm measures 1.25" diameter at widest part of tip, 1.30" diameter at mid-ridge, 1.52" from center of stem to perineum pressure point and has an overall height of 4.75".
