The Dual Vibrating Flexi-Dong is wireless and made of pliable soft jelly. This incredibly flexible double dildo has an adjustable vertebrae and each dong has an insertable length of 7”. The diameter of each vibrator is 1.625” and is shaped like a penis to give you that real feel. The middle has a push button finger tip activation that allows for three separate vibration and pulsation options. The controller requires 3 AA size batteries, not included, to provide this double ended vibrating dildo with powerful vibrations. Sometimes, it takes two to get the job done! CALIFORNIA EXOTICS
