Storage bags

A bag, comprising:

• a back panel;
• at least one flap extending from the back panel, wherein the back panel and the at least one flap extending from the back panel lie substantially flat when in an unzipped configuration;
• a zipper attached to and extending around an outer edge of the back panel and the at least one flap extending from the back panel, wherein the at least one flap comprises at least one of a first side panel, a second side panel, and a front panel of the bag when the bag is in a zipped configuration;
• a first restrictive element for selectively restricting a movement of a first zipper slider along the zipper, the first restrictive element having a first end and a second end, wherein the first end is attached to the bag on a first side of the zipper and the second end is selectively attached to the bag on a second side of the zipper using a fastener element, wherein the restrictive element is positioned along the zipper path at a location between a first terminal end of the zipper and a second terminal end of the zipper, wherein when the second end is engaged on the second side of the zipper, the first restrictive element spans the zipper and is substantially flush to the zipper path, thereby restricting movement of a first zipper slider and preventing the first zipper slider from further sliding past the first restrictive element to unzip zipper when the first zipper slider abuts the first restrictive element, thereby forming a first selectively openable aperture of the bag.
