I bought these vacuum bags solely because of the 17 x 2 x 8.5 inch dimensions. I need the superior filter material they are made from to make face masks and I figured 17 inches would be a hell of a long bag. Perfect. None of these measurements are accurate. When placed on a table they measure approximately 11 inches. long. If I lay the box vertically on the table, they are 10 inches tall, none of which are 17 inches tall. I also don't know what the 2" and 8.5" have to do with it. None of the measurements are correct.
