Hopsooken products are good quality these packing cubs are good quality, the zippers are strong and easy to unzip and zip up. The texture of the bag is very nice.
These 5 packing cubes are rectangle, they are pretty big size. I rolled my clothes to test it out and it fits more than 5 tshirts for the medium bag, The large size i put jeans or sweaters in them about 7 also i can fit. The laundry bag i dont intend to to use it as a laundry but put my shoes in. I dont know what i would put in the 4th bag but the smallest would be personal items such as bras, underwear, socks etc. My luggage has two sides so it will fit perfectly and it doesnt weigh heavy in your luggage so lightweight. If my mom doesnt use it than i will use it. There is a mesh top so you will see what you are looking at
