The present invention relates generally to a container or a carton having a plurality of selectable volumes. The present invention is also directed to a container having a plurality of identified markings to reduce container volume upon partial consumption of content. The container includes a plurality of fold facilitating creases adapted to allow panels to be folded or removed along a fold facilitating crease and/or perforation. At least one set of perforations or identified creases are provided in the box so as to form a shell and a second or a secondary box, where the shell is removed after the contents of the box have been partially consumed and space becomes available. The container may further include perforations, flaps, tabs, slits, indentations, notches, along or at an edge of the panel. A blank of bendable and creaseable material for forming a predefined selectable volume carton box is also disclosed.
