Before being taken out on the court, our balls undergo several tests. Lab tests check elements like the quality of its bounce, hardness, sizing, etc... Field tests are conducted with our partnered testers to evaluate the performance of our products in real game conditions. These balls are approved by the ITF (International Tennis Federation).
Use the balls within 2 months of opening the tube. De-pressurised balls lose their bounce after 2 months without use.
