The natural vagina has a series of ridges called rugae , and manufacturers often add nubs or ribs into artificial vaginas to simulate the rugae and enhance pleasure. Vibrating bullets are usually controlled by a panel connected by a wire. Make sure you cut evenly, so that there are no jagged sides. Condoms and latex gloves are the best contact surface options, but buy good quality, especially latex gloves as the cheap versions tear easily. The artificial vagina as a sex toy is designed from the materials that maximally imitate the natural skin.
