Play sand is a fine sand that has been professionally graded for usage in playgrounds, activity areas, and children's sandboxes. To make it safe and soft for small hands and feet, it is usually cleaned, screened, and dried to get rid of dust and contaminants. Play sand is non-toxic and smoother than construction or builder's sand, making it ideal for sensory play, digging, and shaping. https://texasgardenmaterials.com/product-category/landscape-materials/sand/
