These delightful, light catching Mobiles are hand made one at a time by Aly. Every piece of color on each one is a different form of glass. The bars are made of aluminum and they are held together by swivels. These kinetic sculptures can move in dynamic compositions but do not make sounds. They can be placed indoors or outdoors. The lengths are meant to give a general idea of size but may vary as they are made. You will receive the exact mobile pictured here.
