This Flat 2 Mil Poly Bag Assortment has the right size every time - and plenty of left over bags on hand. Their use is as vast as your imagination… for carrying different weighted items when hunting, fishing, storing craft projects or just keeping things under control. The smallest bags are great for parts, pins, springs, screws or any other small items in or out of the building. Perfect for organizing parts after polishing or finishing or just plain ole' storage… bigger bags for larger parts or hardware and the largest will hold some of the larger items around that either need protection form the elements or just for a neat clean shop.
