the valve of the balls you purchased must be lubricated with vaseline and inflated using a ball needle. The air should be manually controlled, and when it reaches a good level, the air pumping should be stopped. First, it is necessary to insert the needle of the pump into the ball valve and press air with the pump. It is necessary to continue this process from time to time until the required level is reached. It should not be pumping more air into the ball to the required level and the needle should be removed at this point. It should be between 0.6 and 1.1 atm ( kpa, 8.6 to 15.7 psi). This advice applies to balls for all sports. It should definitely not be inflated with tire inflation devices used in gas stations. High pressure devices can cause serious damage to the balls. Therefore, the product is out of warranty.

in the case of the valve slipping due to forced without using a needle, falling into the ball, it is not possible to exchange or return the ball.
