The Constructive Playthings Exclusive 4 in 1 Rainbow Stacking Set is a versatile early learning tool designed to support multiple developmental skills through hands on play. Perfect for classrooms, therapy settings, and home learning environments, this engaging set allows children to stack, lace, count, and match shapesall with one beautifully crafted wooden toy. The set includes six wooden square blocks that vary in size and are stained in vibrant rainbow hues of red, orange, yellow, green, light blue, and blue. Each square features a natural wood inset with a removable shape and corresponding peg holes that can be used for stacking or threading activities.
