We love our packing cubes! We have a mix of brands, our biggest cubes are from Kathmandu and some smaller ones from Aldi (could've sworn that I had another brand too but thinking about it, I dont think so)
We have a cube each for formal, another cube for swimming stuff, another for warm clothes and another for casual/general/undies etc and then an empty one each for dirty laundry. We roll everything. We also have a cube each for Embarkation day that goes into our carry on bags with 1 lot of swimwear, meds, phone chargers/adapters and a change of clothes for first night dinner.
