The feeling is surreal! This waterproof Lucid Dream #9 is made of soft jelly. The curved vibe measures 6.75"inches long and has a ribbed diameter up to 1.5"inches. The multi-speed vibe 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!
