TengaÕs stylish take on a classic vibrator shape is equally suited for internal or external stimulationÑthe firm-shaft silicone vibrator is topped with a soft, squishable sphere of dual-layered soft-touch silicone. This flexible tip can move during use, offering unique sensations, while its lovely wave-like design element offers subtle texture during use. Perfect for users who prefer low-to-medium-range intensity levels Ð vibration in tip are more diffused than those of the firm shaft, so you can explore angling the toy for just the sensation you want. One-button controls turn the vibe on and off and cycle through its vibration modes (three intensity levels and one rhythm pattern). Takes two AAA batteries (included). Use time: 4 hours at maximum strength. Waterproof, with anti-dust coating that keeps the vibrator clean when not in use.
