I had no idea how useful packing cubes would be! On our last trip, I put socks and undies in one, shirts in another, etc, and at each hotel I'd just move the cubes into drawers and voila, everything was organized and easy to find. It really saved time and prevented the mess a suitcase full of clothes and stuff can turn into. This is one of those products that really make a difference when travelling -- I'll never pack without them again. Good quality, highly recommended!
