Mystim Little John Butt Plug Small. With his compact diameter of 4 cm, Little John is the Mystim Butt Plug perfectly suited to get started with anal fun. The smooth metal narrows, so that the butt plug can be easily inserted. Thanks to the fact that the separation of the plus and minus poles is located only a few centimeters from the tip, the soft tingling, rhythmic pulsating or sensuous pushing sensations can be felt very soon after insertion. The stimulation can be enjoyed for hours or quickly lead to new and unexpected orgasms. Little John is made of medical aluminum and polished neatly by hand. For extra kicks, it can be warmed on the heater or cooled in the refrigerator: it is designed to retain the temperature for an extended period of time. Crafted from hand polished medical grade aluminum. 24 month warranty. Please note you will require an e-stim device like the Tension Lover, or the Mystim Pure Vibes to activate the poles. 9.0cm by 4cm, 180g e or approximately 3.54 inches by 1.57 inches, 6.35 ounces standard US units.
