I love these packing cubes? They make it so easy to keep my suitcase organized. I would typically roll all my clothing to make it fit better but would always have to dig for a certain item and then my suitcase would be disorganized. These cubes make it easy to stay organized which is great for us because most trips we fly there/back but end up staying in a couple different hotels along the way sonI need to repack my suitcase every 3 days or so and these cubes are a lifesaver! Only reason to give 4 instead of 5 is they are pretty thin. This is great for luggage weight restrictions but Im not sure how long they will last. Mine are still pretty new (used 4 times).
