Sturdy magnets hold the mirror to the inside of a locker or onto other smooth metal surfaces such as a refrigerator. Locker mirror is made with a durable reflective acrylic that is shatterproof and virtually indestructible. Polished frame edges are smooth to the touch to prevent cuts and scratches, and safe for a child's little hands. Makes a great addition to a locker at school, work or the Gym.
