Very practical and discreet cases due to their color, for situations where you have to place them somewhere visible. The inner transparent compartment fits a lot of clothes; when you suck the air out with a vacuum cleaner, the height of the stack drops impressively, and if you fold the clothes nicely, even after six months they don't come out wrinkled. Personally, I also put a scented sachet inside before sealing it. Just be a bit careful: if you put a lot of clothes inside and lift the outer case by the handles, it's only a matter of time before it tears, so it's better to lift the whole thing from underneath when it's full.
