Question 6/6 in Questions on the product details FAQs
The minimum weight of the ball is 50gms and does not include the label or the post pack bag. We allow an extra 2gms per ball to ensure your package is not overweight when posted. Australia Post will return overweight packages to us and this would lead to a delay in delivery.
Example: it is not possible to ship 10 x 50gms balls in a 500gms post pack bag.
