12 months & up. Encourage children to recognize and understand facial expressions and emotions with a set of mirrors. Each one in this 8-piece set has a shatter-resistant mirrored side so children can see their own faces, and a real photo of a child on the other side. Children will be able to start to make connections between facial expressions and emotions, develop empathy and build social-emotional skills. Each mirror measures 6"L x 6"W.
