Package the object carefully, with plenty of padding.
Write the recipient's name and street address on the package.
Write the country name in large letters.
Request the postal code for the package's destination at the post office.
Ask for price quotes on sea and air transport. Sea is cheaper but can take much longer, especially when traveling between continents.
Expect to pay an expensive surcharge, often up to $30, in addition to the weight if you request rush delivery.
Insure the package for its real value.
