Transform outdoor play into creative expression with this three-piece chalk brush set. Each brush features a water-activated chalk powder core that activates when dampened, allowing children to "paint" vibrant designs directly onto sidewalks, driveways, and patios. Simply add water, and watch colors bloom across hard surfaces. Perfect for artistic exploration, imaginative storytelling, and active outdoor engagement. The set encourages fine motor skill development while providing hours of mess-free, washable fun. Ideal for ages three and up.
