The 4-Rings Basketball Stand with Storage Bag is a great way for kids to have fun practicing their basketball skills. The four hoops each have 18-inch diameters, making them easily wide enough for standard basketballs. They are set at different heights, so that most preschool aged kids will be able to easily make shots, and even slam dunk on the lower hoops. The stand’s 36-inch wide base makes it highly stable, and unlikely to get knocked over. Having multiple hoops makes it easier for kids to practice shooting at different angles, and also lets multiple children play together more easily. A removable storage bag can be set up on the base of the hoops, which gives you a reliable and compact place to store the basketballs when not in use. Replacement bags are also available if the included bag gets lost or damaged.
