These are great-- I use them to hang-dry my socks, stockings and undies when traveling-- also sometimes just to hang my socks, bras, scarves etc off of normal hangers at home and on the road, just to keep them more easily found in my closet. The uses for these are countless! It also helps hold spaghetti strapped items, or those slick silky shirts that always fall off the hanger.
You could even use them to hang dry picked herbs etc-- anything you need to keep suspended. Adjustable and reusable they are a good choice and more handy than I thought they would be in travel.
