A suitcase is easy to pack. They open easily, have straps to hold everything down and will often have additional pockets that you can use.

Toothpaste is considered a liquid by the TSA (Transport Security Agency), even though it's technically a paste. In fact, all pastes, gels, waxes, and lotions are also classified as liquids.

Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.
