Unique Ball Restore
This product is no longer available.
Tennis balls are made with an internal pressure of 14 PSI and packaged in a pressurized can. Pressure is released when you open the can. Once this occurs pressure inside the ball will now escape through it's porous rubber. During play each time you hit the ball it will force the internal pressure even more.
The Restore pressurizer will surround the balls with 14 PSI pressure during storage. Also, if stored for about 4 weeks it will force pressure back into the balls giving them new bounce! This Restore tennis ball pressuriser holds 3 balls and is a must for every tennis bag.
