Using these sand saddle bags is a breeze. Simply unzip the bag, fill it with sand up to its 20 lbs capacity, and zip it back up. Then, attach it to your backdrop stand. When not in use, keep them in a dry place to prevent the polyester nylon material from getting damaged. If they get dirty, you can gently wipe them with a damp cloth. Make sure to keep the zipper clean too so it opens and closes smoothly. Avoid overfilling the bags as it might affect their performance and durability.
