The invention relates to means for carrying different objects by a user. The inventive bag takes a small volume in the fold state thereof and can be used as a small container for carrying small-volume objects. When the lateral sides (2) of the bag are in part unfolded (only in a vertical direction), the bag size is modified in height. Then the lateral sides (2) and the bottom (1) of the bag are unfolded in a horizontal direction, the bag size is modified in length and in width. When the bottom (1) and the lateral sides (2) are totally unfolded in a horizontal direction, the bag size is modified in length, in width and in height, thereby increasing the bag volume by up to fifteen times. The inventive bag-transformer can have many transformation variants without changing the parallelepiped shape thereof, said shape being more suitable for a user, is simple, easy for use and has extended functionalities.
