12” x 48" Rectangular Mirror is made from shatter-resistant acrylic to ensure babies, infants, and tots are playing in a safe environment. Mirrors help tikes develop self-recognition skills, spatial awareness, and improve visual tracking skills as they watch movement. Molded polyethylene corner and side pieces (included) hold the mirror securely to the wall during tummy time and other play activities. Installation is simple. Additional mounting hardware is not included.
