I had searched for Mailing
I had searched for Mailing tubes on Amazon, but couldn't find ones of the correct length and diameter. U-Pack had a decent choice, but I wish U-Pack would take suggestions for other sizes and diameters. For example, to mail posters of say 2ft width (24 inches), the tubes should be 26 inches in length so the edges don't get crushed by the end-caps. Also, 3 inches is a much better diameter, where the posters won't get damaged by being rolled too tightly.
