Abstract: A bag closure system for automatically closing a bag with audible and tactile feedback to indicate proper closure of the bag. The bag closure system includes a bag device having an opening, a first band positioned within a first lip of the opening, and a second band positioned within a second lip of the opening. The first band and second band are comprised of a resilient elongate material that audibly and tactilely indicate when the opening is opened or closed. The first band and the second band further provide for automatic closure of the opening to prevent loss of items within the bag device. The first band and the second band are preferably comprised of a resilient material having an arcuate cross section providing rigidity to the bands when in a straight condition.
