Wanna maximize closeness and firmness while enjoying some very good vibrations? You'll want to snap up the 5 Bead Maximus Rechargeable Ring, then.

Not only does the 5 Bead hand you and your partner a silkily snug beaded ring that'll help support and intensify an erection (or enhance a favorite strap-on), you'll also have twelve modes of super powered vibration to share. Vibration comes courtesy of a full size embedded bullet surrounded by lots of silky, mega-textured silicone.  A simple button accessible by either partner activates and varies the rhythm. 

In high end hypoallergenic silicone, Maximus is body safe, virtually maintenance free and extremely easy to clean. Before and after playtime, scrub your ring under some warm soapy water, or use a favorite toy care fluid/foam. This Ring is compatible with any great quality water based lube, but please avoid contact with silicone lubes and other silicone toys/products. USB rechargeable, cord included. Waterproof. 

* Ring stretches from about 2.75"/7cm
