The Murani Montessori Mobile for baby is a beautiful decoration item made of black and white geometrical shapes balanced off of a glass ball which reflects the light. I stimulate the visual sense of a newborn.
It introduces color contrasts and it's fascinating as it moves in the breeze. 
The Murani Mobile helps the newborn (0 to 4 months) develop his visual abilities and stimulates focus and concentration.

This is not a toy. You should never let your child play with it. The mobile should be hung at 30 cm distance from the child's eyes. It is meant to be observed, not grasped.
