Post Office factPackages weighing up to 11oz. can be sent by first class mail for quick service. Packages over 11 oz. can be sent by priority mail which usually takes 2 days to arrive to the destination or by express mail which takes 1 day. Packages weighing 1lb. (pound) or more can be sent by parcel post, or fourth class mail, which is less expensive but takes considerably longer to reach the destination.
When wrapping packages, do not use string or scotch tape (glue and heavy packing tape is preferable). You must wrap the package yourself. While post offices do sell large envelopes and containers for packing purposes, postal clerks will not wrap the package for you. It is best to wrap packages in a large envelope or plain box. If your box has writing on it, you can wrap it in plain brown paper (you can cut up brown paper bags from the supermarket, for example). Be sure the address is clearly marked and easy to read.
