The SIZE of the net contents statement is important.
The size of the net contents statement is based on the size of the principal display panel. If the principal display panel is more than 5 square inches, the required size for the net contents statement is 1/8″ high. Generally, that would be any product over about 4 ounces. If the PDP is less than 5 square inches, then the text of the net contents can be 1/16 inch high.
