The Vibrating Bulb Anal Plug is a really good anal toy to get used to bigger sizes due to the bulb in the middle of the shaft. The shaft has 3.75 inches of insertable length and 4 inches of girth at its widest point. It is made of a smooth silicone that is easily insertable. The anal plug is controlled by a remote control which has 31 inches of lead length so that there is no trouble when changing the vibration mode. While the remote control isn’t waterproof, the anal plug itself is so you can safely submerge it into water as part of your play!
