Incredibly handy! This unique dispenser holds 321/2' of wound polyethylene film, but still fits in the palm of your hand. Just pull the plastic bag material from the center of the dispenser, take the length you need, cut it with the built-in safety cutter, and tie a knot in the end to create a bag of any length. Great when boating or camping for taking care of laundry, garbage, wet swimsuits, food storage, and much more. Dispenser is only 4" high.
