Shipping costs are outrageous these days, and if you have a product that is shipped to multiple locations the cost of repackaging it could really chip away at your margin. Selecting a wood box can not only protect your product it can be used time and time again.
Simple upgrades to your box such as link locks, forklift steel and paint can add years to your investment. It also makes the statement that your product and customer are just a little more important than the rest. Long term reusability can slash hundreds from your packaging budget as opposed to the one way shippers that have to be reordered the next time, and the next, and the next, well you get it! Like the American spirit, the durability of wood and a well constructed box will last for years.
