This model is designed to be blown through a tube with the mouth, and the size may vary due to the differences in blowing by different people.

If you are very concerned, please be cautious when taking a photo.

If the size of the ball is off, you can use the air pump for the yoga ball. If you step on it with more force, you can inflate it several times.

Size and weight deviations are not quality issues, so return shipping costs are the customer's responsibility!
