It's a real gem! The Power Gem is made of soft jelly material. The gyrating shaft measures 6'' in length and has a ribbed diameter of 1.5''. The shaft also has free-floating internal beads for an extra slice of heaven. The clit teasing duck has a separate bullet for two-speed vibration. The base of the vibe houses the multi function controls. Requires four AA size batteries, not included. Power up your fantasy!
