NPG Extreme Pleasure Hip Mini form has been scaled down to hand held size for the Mini. The material construction is a core type two layered tunnel and closed ended. Dual-layer design is where the tunnel is made from a different material than the rest of the item. This type of design allows for one material that may produce a better tactile feel on the outside while another for a better stimulation during use.
The tunnel design of Extreme Pleasure Hip Mini is similar in design to the newer iterations of the series with organic looking nubs, nodes, and ribs throughout the straight tunnel. The path narrows and become tighter at the last quarter of the tunnel for a tight end.
