These are our 2" x 8" 2 Mil blue line economy zipper plastic bags. The only difference between these 2 x 8 .002 mil zipper lock bags and our 2 Mil Clearzip bags is that these are in limited quantities. These 2 in. x 8 in. 2mil zipper bags have a light blue line that runs through the top of the bag, just above the reclosable seal.
