This beautiful Treeze Smooth Vibrating Wood Pleasure Wand wood/urethane hybrid material creates an ultra smooth, nonporous, phthalates free surface that is lubricant friendly and is waterproof. Because the fibers of the wood are saturated with urethane resin and are cured under pressure and at high temperature, you can rest assured that there will be no splintering. The 1 1/2 average diameter wand features an ultra smooth shaft and an approximate 8 usable length. Two AA batteries are required for operation and are included. Proudly manufactured in the U.S.A. Another revolution to the industry is a replaceable vibrator. Don Wands now offers the first replaceable vibrating wood pleasure wand in the world. Treeze Wood Pleasure Wands include a sample pack of WET® Platinum Lubricant and a tan padded pouch for safe storage
