This Ball Doctor quart will last for a while. Ball Doctor seals leaks and punctures in all valve inflatable balls without a bladder. Just fill the included syringe, insert the syringe in the ball valve and depress the plunger. Pump up pressure and bounce the ball. That's it... It's fixed. It only requires 1 oz of ball doctor to repair most balls. A quart contains 32 ounces.
