The Do Art Pottery Studio set includes a pottery wheel and a fully illustrated instruction booklet. The wheel surface is grooved which helps to hold the clay firmly and keep it centered. The pottery wheel uses a foot pedal operation, which means no onoff switch to worry about, so your batteries will last longer Requires 4 C batteries not included. The Pottery Studio refill contains 2 lbs of air dry clay, 6 pots of acrylic paint and a paintbrush. The refill can be used with or without the Do Art Pottery Studio. For Ages 8 Important Note this pottery wheel is a high quality children's craft product. Although the function is similar, it should not be compared to professional pottery wheels.
