Pfun is designed as a man's toy. It is curved to hit and massage the prostate. However, the curve manages to hit the G-spot as well. Pfun, like all other Njoy toys, are made of stainless steel. The surface is extremely slick, shiny, and smooth. Pfun can be worn for long periods of time, but the design makes it kind of difficult to keep in. The sphincter plays a tug of war game with this toy, and it feels awesome. The handle is just as comfortable as the other Pure Plug handles.
