GONGE River Stones Set of 6

2 years & up. The River Stones are designed to improve coordination and balance. Jumping or stepping from stone to stone developes a child’s confidence in their ability to judge distances. The side of each triangular block varies in steepness and difficulty, and the layout can be changed to make a pathwat more or less challenging. Each stone has a non-slip rubber rim that helps with stability during play, which also protects indoor surfaces. River Stones can be conveniently stacked for storage. Each set includes 6 stones in 6 colors: three measuring 14.96″ x 14.56″ x 3.35″ and three measuring 10.23″ x 10.23″ x 1.77″.
