It was made out of Industrial Heavy Strap Material to form a ball. The 18-inch strap ball comes apart into two pieces for easy shipping and decorating. Can be used separately or together. We recommended connecting it together with wire. It can be hung or placed inside pots. The 18" diameter garden sphere is made with a wide metal strap. Great Look and a Great Price. Use this metal ball out in your garden or place it on the mouth of a planter for unique container gardening. We carry many sphere sizes if you want to do multiple sizes.
