Our 'Vented' product line has been developed in order to avoid the USPS surcharge while efficiently using the space given within a single cubic foot. Instead of making a 12x12x12 box, for our new 'Vented' Single, we've traded four inches on the width in order to add 6 inches on the length and still remain under one cubic foot!
Horizon has managed to deliver the most value per inch compared to the competition.
