This set includes 5 bags in two types.
Type1 are bigger and with depth, so you can have your clothes categorized into different functions (say pajamas, outfits, socks, etc..) and squeezed them into different size of bags; or you can also categorize them into ready to wear/ready to wash. The net on top is made for evacuating extra air, so you don’t need a vacuum to have your clothes efficiently packed.
Type2 are pretty easy to understand, they are smaller, mostly for your cosmetics products, or personal cleaning items (say tooth brush, lotions, etc.).
If you are interested in being some unique traveler with eye-catching equipment to impress your partners, these are exactly what you are looking for! You probably wouldn’t be able to find these products in decent brown and vibrant blue anywhere else. Let’s be honest, travelling is fun, but packing is not, save your time on packing so you will have more time for travelling!
