The Silky Stud Vibrator is a wonderfully realistic feeling vibrator made of silky-soft jelly material with a lifelike shaped penis head. Firm, yet pliable, this vibe has a ridged shaft for extra pleasure. Operate the variable vibration speeds using the twist-dial base. This studly vibe even comes with a handy tote cord. Uses 2 AA batteries, included courtesy of the Sinclair Institute.
