The Lavender 6 Pak is an amazingly versatile set of stimulators and sleeves. There is a 6" X 1" multi-speed massager with a jelly sleeve. This vibe uses 2 AA size batteries, not included. The 4" X 1" multi speed massager has 3 different shaped sleeves and uses 1 AA size battery, not included. It's time to have some fun!
