Great Product But Counter to USPS Size Requirements

I love Sticker Mule Poly Mailers and have used bunches of all three sizes. Having said that, the largest size, 14.5" x 19", is longer than USPS rules allow for poly mailers. According to the USPS rules, "For envelopes larger than 18″ in either direction, you must use the box package type and enter all 3 dimensions of your final package." This somewhat defeats the benefit of shipping with poly mailers. If I were to make one suggested improvement, shorten the mailer to 18" to meet the USPS requirement. You really lose very little usable room within the mailer and get a much better shipping rate with USPS. I actually fold over the bottom inch of the mailer and tape it so the mailer measures 18" long when I use them. Just a thought.
