I am shipping movie posters in 3 inch tubes. How do I enter the
measurement, for length width and height. height is 16" long, width is
3" diameter what is length 3"? I mark irregular package size
Thanks for the info. But the question is what to enter in the length,
width and height for tubes. the tube is 3 inches in diameter, 16" long
but what to enter as height? 3 inches?
