This black hardplastic plug has two conductive metal strips running down the sides so it's a bipolar toy. When you connect the plug to an electrobox, the current running through your rectum will cause your sphincter muscle to alternately contract and relax in the same rhythm as the pulse: a fucking great feeling.

On the baseplate of the plug are two 4 mm bananasockets for connection to your electrobox.

Sizes: insertable lenght 120 mm, diameter max 40 mm min 25 mm.
