Although it's possible to use things like bubble wrap and poly mailers to create safe packaging for something like a small picture frame or other relatively flat object, for larger items which require a box, there are a few things that should be done to ensure that everything inside a box arrives at its destination intact. An aspect of safe shipping that many people completely forget is that large, hollow items may break even if they are properly insulated on their exterior if they are not also properly supported from within. For example, a vase should be stuffed with paper so as to prevent it from being smashed.
