Bowie and Queen, Jay-Z and Linkin Park, Run DMC and Aerosmith: proof that big duets always work. A harmonious meeting of two luxury sex toy giants, Doxy and Nexus have collaborated to bring you an attachment in a league of its own. Unlike other massage wand attachments which slip directly over the head of your wand, Doxy have crafted an innovative solution for easy customization. With the Doxy Number 3, you simply unscrew the head of your wand, replace it with your new attachment, and away you go! Once set up, coat the shaft of your toy with water-based anal lube for smooth insertion. Please note: This attachment is waterproof for easy cleaning, but your massage wand is not. Always detach the attachment from your wand before cleaning.
