Balls used in ball games can be surprisingly bulky and difficult to carry, right? I think there are many situations where you might need to bring a ball, such as for your children's club activities or when playing outside with your family (^ ^) When carrying them as they are, you might worry about them rolling away and causing an unexpected accident (^ ^) In such cases, a ball net like this is convenient (^^) If you want to have fun, why not eliminate those hassles and worries with just one net? (^^)
