Lumia 沙袋 5kg 預填充即用型 適用於燈架、C型支架、吊桿臂、平衡重 攝影沙袋

The metal beads are packed tight enough that the bag keeps its shape on the stand, which makes balancing a boom arm feel way more stable than loose sand I've used before. It's heavy for its small size and slips under a light stand base without taking up floor space.

These things are solid. The metal beads inside make them way less messy than traditional sandbags, and they sit perfectly on my C-stand legs.

I was a bit skeptical about sandbags for my light stands, but these metal bead-filled pouches are so much neater than loose sand. They're pre-filled and ready to use, which saved me time setting up for a shoot, and the 5kg weight holds my C-stand boom arm steady even in a slight breeze.
