The feeling is surreal! This waterproof Lucid Dream #18 is made of soft jelly. The vibe measures 8.75in long and has a varying diameter up to 1.5in. The four-speed controller requires two AA batteries, not included. This virtually silent personal massager is smooth and designed to please the eyes has well as the body. This collection is wildly abstract and wickedly erotic. The colorful and twisted shape vibe is sure to find its mark!
