With 6 insertable inches and 10 vibrating functions, this harness compatible dildo is ready for extreme fun. Made of our unique X5 material, Hard On with Vibration has a realistic feel that mimics the soft/firm balance of the human body. The molecular bonding of X5 allows it to be flexible, yet highly resilient. This means that X5 has memory and can recover its shape. The vibrations are controlled by a convenient remote (using 2 AAA batteries), so you or your partner can be in control. Hard On with Vibration is also waterproof and phthalate free.
