Artists have long reinvisioned everyday items to create new art. The Flying Wall Bowls were born out of this tradition. The iron wall bowls have enamel interiors and painted bronze colored exterior. Each color is sold in a set of three (small, medium and large). 1/1/4" disc with a threaded pipe easily screws in the wall to hang each wall bowl invisibly and securely. The wall bowls are wall decoration only. They are not intended for food and are not food safe.
