What to keep in your carry on bag
The right toiletry kit will hold all your essentials without taking up too much space in your travel luggage.
Keep these tips in mind when packing your toiletry kit:
Think small: Current travel rules in the United States require that containers of liquids or gels taken in a carry-on bag weigh no more than 3 ounces. Even if you are packing your toiletry kit in checked luggage, buy small-sized toothpaste, shaving cream, deodorant, and other personal care products to save space.
Think conversion: If you are bringing any appliances, such as a hair dryer, on an overseas trip, be sure to include the right conversion plug in your toiletry kit or in your carry-on bag. You can't count on being able to buy the right adapter when you arrive at your destination.
Think emergency: Other useful items to include in your toiletry kit are a small sewing kit, a few clothespins for hanging laundry, and a small multi-tool, such as a knife/bottle opener. Just remember not to put your multi-tool in a carry-on bag if you are flying.
