This cone shaped anal plug is a thermo reactive plug, which means it gets softer when heated, and harder when cooled. The inner core is filled with Silexpan. The exterior is soft and lifelike silicone. This ensures a higher flexibility and dual density: soft outside, hard inside. Because of the suction cup base, the plug sticks firmly to any smooth surface. It also enhances the sense of security while using the anal toy.
