STOCK TIPS

Once you've depressurized your bullet tube, you'll need to use your bullets for less than 1 month, as they lose their yield after 15 days without use.

TESTS

Before they hit the field, our balls undergo several tests.
Laboratory tests validate the following elements (mass, diameter, compression and rebound height).
Field tests are carried out with our partner testers to evaluate our products in terms of game feel, liveliness, control, resistance and rebound stability.
