You'll use these to make Ranger/Sapper Purses by covering the outside of these bags with 100 MPH tape, which will serve as your pocket sized wet weather bag. You can also use these as a improvised map case by lining the edges with 100 MPH tape and leaving a tail on one end that you can attach 550 card to.
This is something you don't want to go cheap on. The average sandwich bag is 1.5 mil in thickness. Most freezer bags are around 2 mil in thickness. Ziploc brand freezer bags are some of the thickest at 2.7 mil.
These bags are 9in x 12in x 6 mil, over twice the thickness of what you can buy in the store. The single-track zipper closure keeps out dirt and moisture. The high clarity plastic & sturdy construction for easy item viewing and handling. The off-set lip and ridges make gripping and opening easier. They come in a 25-pack and will be worth every penny.
