The Vevor heavy-duty sandbags set includes 50 empty woven polypropylene bags designed for flood protection, storm defense, and general jobsite use. Each bag is built to resist tearing and wear while supporting up to 50 lbs of sand or gravel. UV protection helps the bags withstand prolonged outdoor exposure for longer service life. The wide opening and included tie strings make filling, sealing, carrying, and storage easier. These sandbags are also suitable for construction, landscaping, and dry material storage applications.
