Tennis ball saver container designed to maintain the pressure of tennis balls. This device builds internal pressure to 14 lbs. per square inch when three tennis balls are placed inside, replicating the pressure of a new can of balls. The stored pressure ensures new ball bounce for each match and keeps original pressure when balls are not in play. Dead balls can be rejuvenated in 4 to 8 weeks by storage in this container. The yellow canister features red lettering for the 'Tennis Ball Saver' brand and the slogan 'Keeps 'Em Factory Fresh'. The white base component includes markings for internal pressure in PSI and instructions for periodic maintenance, recommending cleaning the 'O' ring and groove with a soft rag and avoiding solvents.
