Irresistibly thick and hard, the award winning Nexus Excel provides a breathtaking fit to the inner contours of a mans body, perfect for giving a strong massage straight to the prostate. The smooth, durable material combined with the stainless steel roller perineum massager and the external handle makes the Excel equally enjoyable as it is easy to use. The Nexus Excel is made from polypropylene, a non-toxic plastic that is non-porous, smooth and rigid. It is 100% waterproof and can be used with water and silicone lubricants.
