The set consists of a colorful snake made of different types of fabric (corduroy, fleece, etc.) and a blue snake with a small marble in it that can sometimes be seen.
By feeling and experiencing the different types of material, the sense of touch improves. The marble can be pushed through the tube with small and precise movements, which not only improves the sense of touch but also the fine motor skills.
The snakes are also ideal for use as sensory material.
