Enclosures
Bulky items such as pens, pins (lapel or button), paperclips, binder clips, coins or anything that will cause the envelope to assume a distorted shape and rip open when going through standard USPS machines must be placed in padded envelopes or boxes. Pieces deemed unsuitable for the machine will be returned to the department for repackaging.
If you have any questions about a specific enclosure item, please contact Postal Services.
