Nexus Neo is a dual prostate and perineum massager. It's perfect for those more experienced players who know that a little extra length and girth goes a long way. The Neo is made from firm phthalate-free polypropylene which is super smooth on the skin but hard enough for an effective prostate massage. The stainless steel roller ball will deliver licking sensations to the perineum and can be taken out with the tool included to clean. Can be used with water and silicone based lubricants. Shaft length: 13.5cm (5.31ins) Shaft circumference: 9.2cm (3.62ins) *Remove the stainless steel roller ball and replace with the Nexus iStim attachments (Sold separately), connect it to your ElectroSex system and transform Nexus Neo into pure sexual dynamite! * We carry a 1 year warranty on all products.
