Power up your engines ladies - your plaything won't buzz without batteries.
In each toy's Info Box, we list which kind of batteries your toy will need and how many. If it needs AAAA batteries - these are the batteries for your vibrator.
As toys become smaller, the batteries they take are getting more obscure and perhaps more difficult to track down - its unlikely you'll find these at your local corner shop! Once a battery loses power, remove it immediately or it may leak.
