It includes one assembled Gobbi Mobile made of silk. You can choose from three colors: blue, green or yellow. Age: from around 2-3 months or when your baby is no longer interested in the previous mobiles from the same series i.e. Munari and Octahedron. The Gobbi Mobile is the third in the Visual Mobile Series following the Octahedron Mobile. It consists of five spheres. The colors of each sphere change very gradually. After getting ideas of basic colors from the Octahedron this Gobbi Mobile presents how one color can change in different shades. This is how we open the world gradually to a newborn. The size of each ball is 1.57”. Total length of the mobile is around 10.4". The silk we use is real silk threads, not synthetic fibers. It is natural and non-toxic. The shades are so beautiful.
