**Drop-Tested Sandbags:** Our canopy sandbags are the only products on the market that have passed a high-impact drop test, withstanding the force of a 30-pound weight dropped from a height of 3 meters. This demonstrates our commitment to superior quality. **Materials:** We use high-density Oxford fabric with a PVC coating to prevent sand leakage and weathering. Additionally, we use 3-ply reinforced threads from a reputable source to provide superior stitching strength, ensuring the sandbags' durability. **Capacity and Dimensions:** Each bag can hold 30 pounds of dry sand and can also be filled with wet sand, soil, or small gravel. Four fully filled bags can help a 10x10 foot tent withstand strong winds exceeding 40 kilometers per hour. The dimensions of our product are 18.5 inches in height with a bottom circular diameter of 6 inches. The side nylon sticker is suitable for canopy tent poles with diameters ranging from 20mm to 50mm. **NOTE:** SAND NOT INCLUDED. **Color:** Black **Material:** Oxford cloth **Package Contents:** 4 * Top Sand Bags for Canopy Legs **Note:** Light reflection and different displays may cause the color of the item in the picture to differ slightly from the real thing.
