Let's twist again! The Osaki-Op is made of a soft jelly material. The textured shaft of the vibe measures 4.25" in length and has a diameter of 1.25". The shaft of the Osaki gyrates at two speeds. A beaver shaped clit tickler has a flickering tongue to tease your clit. The beaver tickler vibrates at two speeds so you can personalize your pleasure. The base of the Osaki houses the controls for both stimulators. Requires 3 AA sized batteries, not included. Love you long time!
