ON Insane is now available with an added cooling sensation! For some, this may feel even more intense than the original formula because the cooling effect creates an additional layer of sensation. Women may feel the sensation of movement inside the body, plus stimulating, cool pulsations and buzzing directly on the clitoris. This formula is a water-based hybrid and safe to use with silicone and latex products. Ideal to pair with ON Arousal for Her for an even wilder experience.
