Mail Service Center DOES NOT provide packaging materials
or services. We accept properly packaged and marked parcels, and
reserve the right to refuse non-mailable or improperly packaged articles or
substances.
It is the responsibility of the sender to prepare
packages for shipping and provide protection against deterioration or
degradation of the contents.
Sealing
Mail Service Center equipment cannot seal overstuffed
envelopes (max 1/4" thick), manila, invitation style or catalog style
(end-opening) envelopes
Mail Service Center requires envelope flaps to be
DOWN to seal. If you send envelopes that are already sealed,
separate sealed envelopes from the unsealed. If these envelopes are
not separated, damage and delay occurs.
