Use the yellow liners with the Small Tough-As-Nails Sandbag as full size or partially filled to make a bunch of sandbag "weights": fill, fold, and secure with duct tape; coarser-grained sand works best. These liners add strength and security and we recommend them inside the sandbags.
Small yellow mesh polypro liner 18" x 30" (the size of a 100-lb. bag of sand).
