Visual mobiles made according to Montessori pedagogy. They are made of simple materials such as papers, plastic ball, and acrylic sticks, but each of them has specific purpose to assist baby's visual development. It is recommended to be used by professionals who understand Montessori pedagogy and know how to use these mobiles. They are not toys and should not be used by babies without supervision. It is a set of four classic Montessori visual mobiles that includes: one Munari mobile，one Octahedron mobile, one Dancers mobile, one Blue Gobbi mobile. Munari is the first to use in a series of Montessori mobiles. It provides visual experience of geometric shapes and a transparent plastic ball which reflects light. The Octahedron Mobile consists of three basic colors blue, yellow and red. We use transparent sticks instead of wooden dowel in order to help babies focus on the colors and shapes. The three octahedron shapes are made from non-toxic metallic paper. Size of each octahedron is 2.76"*2.76". Total length of the mobile is around 12.99". The Gobbi Mobile is the third in the Visual Mobile Series following the Octahedron Mobile. It consists of five spheres. Colors of each spheres 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. Size of each ball is 1.42”. Total length of the mobile is around 11.81". The Dancers is the fourth in the Visual Mobile Series. It is made from non-toxic metallic paper in blue and silver color. The reflections from the metallic paper and the dancing figures can easily capture baby's attention. It is a beautiful flowy mobile that allows for engagement and focus. Total length of the mobile is around 12.99".
