Find an appropriately-sized shipping box. Boxes of all sizes can be found at the post office. Small boxes suitable for shipping can even be found at your local grocery or craft supply store.
Place the chocolate in the box. If you are shipping homemade chocolate, wrap each piece individually in plastic or wax paper, otherwise the pieces may melt together. Secure the chocolates in the box with packing peanuts or crumpled newspaper to keep them from knocking around during shipment.
Tape all seams in the box closed with packing tape.
Write the destination address legibly, in print, near the center of the widest part of the box.
Write the return address on the upper left-hand corner of the box.
Take the box to the post office. They will weigh it, calculate the cost to ship it and mail it for you.
