The original 9” diameter ball with over five million sold! What’s so great about gerties? Its special texture makes them easy to catch, kick and throw, and its light weight makes it a great indoor ball. Nothing’s better than a Gertie ball to take on a trip because Gertie’s have a removable inflation straw so you can deflate them and pack them in your suitcase. This one comes in red, blue, green, pink and purple. But beware once you’ve caught a Gertie ball you’ll never want to let it go.
