The Vacuum storage bags are as described on the product description page.There are 4 bags in this box. There is a 1 medium, 2 large and 1 extra large vacuum storage bags. This box also includes a hand held pump for those that might not have a hose attachment on their vacuum or for travel purposes. It would be a horrible situation to vacuum seal all of your vacation clothing, get to destination, open, wear and NOT be able to reseal them. I like to use the vacuum storage bags to put away beach towel at the end of the summer. We live on a lake and use a lot of beach towels during the swimming and boating season. I can get so many towels into these. I also do the same with seasonal sheets and bedding. Who doesn’t need more organization and space? I received these at a discount for my evaluation and review.
