The Fun Flex Anal Teazer features two ends that are both suitable for fun. Start out with the smooth tapered shaft before graduating to the beaded shaft which features a tip of just .5-inches to ease entry before gradually expanding to .75-inches. The flexible shaft bends with your bodys contours to hit just the right spot while each end acts as a sturdy retrieval handle for safe and easy handling. Clean easily using warm soapy water or a good toy care fluid/foam. Compatible with any great quality water based lubricant.
