GONGE Riverstones - The Original Non-Slip Stepping Stones for Kids, Primary Colors, Set of 6

The River Stones are designed to improve coordination and balance. Jumping or stepping from stone to stone develops 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 pathway more or less challenging. Each stone has a non-slip rubber rim, which also protects indoor surfaces. River Stones can be conveniently stacked for storage. Each set includes 6 stones in 6 colors: three measuring 14.96in x 14.56in x 3.35in and three measuring 10.23in x 10.23in x 1.77in. The River Stones are inspired by stepping stones in a river with each side of the triangle varying in steepness and difficulty.
