Using this packing cube is a breeze. First, decide how you want to allocate space for your clean and dirty clothes. You can put your pants and shirts in the medium - sized cube to keep them organized. When you wear a piece of clothing, just move it from the clean side to the dirty side. The floating divider makes it easy to adjust the compartments as needed. When it comes to carrying, grab the top handle for a quick and convenient way to move the cube. As for maintenance, since it's water - resistant, you only need to give it a hand wash. Remember, due to sewing tolerances during production, the actual dimensions and volume of the cube might vary a bit from the calculated ones.
