Any inflatable bouncy castle should be fixed with iron drills and sandbags when in use. Especially when indoors, it can only be fixed with sandbags. Sandbags are not any ordinary bags, they must be specially customized PVC bags that can hold 10KG sand.

The size of sand Bag is about 50cm by 50cm. It is double stitched, cross stitching with Velcro open and close end. You can make extra support and reinforcements on the inside. The sand bag has carry handles and tie down anchor point (metal d ring anchor, metal loop).

Such a sand bag will not leak sand everywhere, and has a strong fixation, which can fix the inflatable bouncy castle on the ground. The price is about NZD16, which is very cost-effective. A must-buy accessory for inflatable bouncy castle renters.
