An origami envelope and a method of constructing the origami envelope are enclosed. The origami envelope is quadrilateral in shape. The origami envelope comprises a top layer having a front surface and a back surface opposite to the front surface, and a bottom layer having an exterior side and an interior side opposite to the exterior side. The top layer extends to the exterior side of the bottom layer over a portion of the top envelope side to form a closure flap at the exterior side of the bottom layer.

A storage and transport system for containers of liquid, comprising a detachable or separable handle component configured to securely hold or enclose a liquid-holding container and provide a carrying handle therefor; and a self-sealing receipt or label configured to receive printed information regarding the contents of the liquid-holding container, wherein the self-sealing receipt or label cooperates with the carrying handle to securely close the handle component around the liquid holding container, and wherein the self-sealing receipt or label is configured to provide visual evidence of tampering if the self-sealing receipt or label is separated from itself.
