  • Testing

    Test product

    Samples regularly undergo shooting tests to confirm the quality of our products. A machine throws the ball 1,500 times against a steel plate at about 50 kph. At the end of the test, the quality of the ball is assessed according to its exterior appearance and various measurements of its spherical shape.
