Guidecraft Rainbow Sand Blocks by Guidecraft
These Rainbow Sand Blocks are an adventure in color, light and sound! Indulge your child's appetite for exploration by merging blocks together to form new colors and sounds, or stack the blocks in a different order each time to form new and exciting shapes. Eight blocks per package. 4 rectangle and 4 half moon shapes.
To clean, use mild soap and water on a damp cloth. Do not use window cleaners or cleaning abrasives as they will scratch the surface and could damage the protective coating.
