This Vibrating Slimline Anal Rocket is a powerful little vibrator with a 6" x .75" Jel-Lee sleeve. The slender pliable probe sleeve has a slightly bulbous tip followed by swells and ridges down its shaft. 1 AA battery, not included, powers the robust vibrations. The vibrator can be used with or without the slimline sleeve. Just coat the sleeve inside lightly with lubricant and pull it onto the vibrator and have yourself an assiliscious good time!
