Endure offers an additional layer of excitement. Made from ultra-stretchy SEBS material, the concentric rings comfortably accommodate the whole package–under and over. The Endure contains a removable bullet–which commands 15 vibration functions–and comes equipped with a remote control that allows the user to cycle through each function. When activated, the remote control has the ability to vibrate in tandem with the ring, allowing a partner to experience the sensations, as well.
