When you need to protect the items that you take on a plane or boat, use something like a Pelican case. These are ideal to hold documents that you might need when you arrive at your destination. The cases can also be used at your home. Important papers like birth certificates, licenses and passports can be kept safe.
A case like this will safely hold a camera so that it doesn't get damaged. This is a benefit for those who work in photography so that their equipment can be carried from one location to another. They also protect computers, something that can cost quite a bit of money depending on the brand and what the computer is used with. Packing materials are placed in the cases so that there are compartments for cords that will keep them separate from the other items. They are watertight, making them ideal for taking on a trip that crosses water. The cases are also corrosion proof. You won't have to worry as much about the case deteriorating from rust as you might with a metal box. Some companies will replace the container if it breaks. Most boxes open from the top so that you know which way to carry the case when traveling.
