Packing aids keep clothing, accessories and other items organized and secure inside luggage. Toiletry kits are an absolute essential to prevent liquids, gels, lotions and powders from leaking or spilling. Many travelers make use of miniature plastic bottles to take small amounts of things, like shampoo and conditioner, as a means of saving space. Individual containers should be packed in an airtight, waterproof bag. For small, valuable accessories like earrings, watches, rings and necklaces, use a jewelry pouch with separate compartments to prevent items from becoming entangled and damaged. Packing squares, cubes or envelopes, in various sizes, will divide and separate miscellaneous objects including underwear, ties, scarves, socks and shoes. A small first-aid kit that contains prescription medications, aspirin, bandages, a splinter picker and iodine will come in handy in case of an emergency. Shoe bags and laundry bags are handy way to transport shoes, wet swimwear and to keep dirty laundry away from clean clothes.
