What Packing Cubes Actually Do
Packing cubes do not create more luggage space by magic. Their real advantage is organization: clothing stays grouped, compressed enough to remain tidy, and easier to move in and out of a suitcase without disturbing everything else.
They are most useful when you unpack repeatedly during a trip or share a suitcase. If you already pack lightly and stay in one place, they may solve a problem you do not have.
