Similar to the Sensory Matters Marble Mazes, the Marble Tunnels use your fingers to guide the marble through the stitched tunnels. The Marble Tunnels have the added benefit of the children being able to see the 10 marbles included at the start and end to the tunnels (marbles are enclosed in the tunnels). In doing so, children are working on their fine motor skills and improving the strength and dexterity of the small muscles of their hands and wrists, as well as being able to fidget with their hands without disrupting others around them.
Sensory Matters' Marble Mazes make excellent fidget toys, particularly in the classroom environment but due to small parts are not recommended for children under the age of 3.
