Soft and pliable, this Jelly stimulator has two flexible probes, one for the front and one for the rear. It's ultra powerful, multi-speed, multi-orgasmic and operates on 2 AA size batteries, not included. The 5" penis is 1" in diameter while the rear probe is also 5" in length with the anal beads being 3/4" in diameter. The vibrator sits right at the base of the probes so the dual stimulation is incredible!
