Powerful yet practical, this smiling-caterpillar shaped vibrator is a great first toy for beginners, but it's one you'll still be going back to many years, and vibrators, later. Among the reasons for that is its sensuality; the shaft is made out of silicone and is broadly ribbed-like a caterpillar. It feels plush yet firm, but with a little flexibility and resiliency. This caterpillar's waterproof, and we know you'll take advantage of that because using this baby in the tub can add a whole new dimension of sensuality to your orgasm. Total length is 5 inches with an insertable length of 4 inches. Requires 2 AAA batteries not included.
