Mailing tips
Print names and addresses of both shipper and recipient clearly on packages with a pen or permanent marker.
Put an extra label with the addresses inside the package in case the original one is defaced. Also include an itemized list of contents.
Select a box strong enough to protect the contents and appropriate for the amount and size of items inside.
Leave space for cushioning inside the carton, using bubble wrap, Styrofoam peanuts, or newspaper to protect the contents.
Use tape designed for shipping, using enough to secure the opening and seams of the box.
Put newspaper or packing material in hollow items to avoid damage during transport.
Write “fragile” or “perishable” on packages when shipping such items.
Use boxes, envelopes and tubes the post office provides for Express Mail and Priority Mail.
