Made of durable, heavyweight melamine, this 10-Piece Mixing Bowl Set includes five perfectly sized bowls with lids for everyday functionality and charm. Offering the classic look and feel of ceramic, these BPA-free melamine bowls are sturdier, resisting breakage and warping when dropped or in the dishwasher. The nesting design provides easy storage while the nonslip ring on the base of each bowl gives added stability to enthusiastic mixing.
