Meet your new best friend in packing. Tuck socks, undergarments, accessories, or charging cables slash odds and ends into this versatile, small cube. This minimalist sanity-saver separates anything you need in a neat, perfectly sized package that slips snugly into any suitcase—or toss it in your tote or personal item (it makes a generous headquarters for travel snacks). A mesh window lets you see inside, so you'll never again have to dig around an unorganized bag. You're going to want more than one.
