Sand-in-a-tube® is dried coarse sand that is an eco-friendly option to spread on walkways to improve traction in winter and prevent freezing. Each bag weighs 45-pounds for the ease of moving to its desired location. The durable tubular bag design will hold up in bad weather conditions and repeated handling. It lays nicely alongside the rear axle, above wheel wells in truck beds or car trunks, and it can hold temporary fence posts and sports equipment.
