Abstract: A mating closure system includes a first closure element and a second closure element, where at least one of the closure elements includes a cut-out opening. Preferably both closure elements include matching cut-out openings. The cut-out opening may be formed in a variety of shapes, but an arc or elongated oval is preferred. The first closure element is placed adjacent an opening of a bag. The second closure element is displaced from the opening, such that when the bag portion adjacent the opening is folded down the first and second closure elements mate with the cut-out openings substantially aligning to form a handle with a resulting notch for accommodating a user's fingers.
