To guarantee the security of your goods on their travels, we advise you use the most robust boxes available. That's why Seven Seas Worldwide offers unlimited, purpose-built shipping boxes with your order, as these are made from chemically-hardened, double-walled cardboard and designed to withstand long overseas trips. However, if you're thinking of using your own containers, here're a few types you should avoid:
Plastic storage boxes
Bin liners
Laundry bags
Used boxes like those used to carry food items or papers and files
