  • "4in1" bag collection
    Publication number: 20050103410
    Abstract: The “4in1” bags do not have a front side or a back side. The flap is fixed in the middle seam on top of the bag and can be swung over to either side of the bag body. Both sides of the bag body and also both sides of the flap are colored differently. Therefore four different color combinations are possible. Very simple, just by turning the bag body and swinging the flap over. From plain black to striking colors, the user can make his or her own choice.
