In this review of the interdepartment envelopes with string tie, the bottom line is clear: these are practical, reusable office envelopes built for routine internal routing and document storage. The reviewer finds them particularly useful for teams that circulate physical paperwork between departments because the heavyweight 28lb manila stock feels durable and the string and button closure keeps contents secure. For offices that need a reusable, easy-to-organize envelope sized to hold documents up to 10 in by 13 in, this set offers a straightforward, no-frills solution.
Key Features
- Durable construction: The 28lb manila stock stands up to repeated handling, so envelopes can be reused instead of discarded.
- String and button closure: The tie closure secures documents during transit and is simple to open and reclose without adhesive.
- Document capacity: Each envelope stores materials up to 10 in wide by 13 in long, accommodating standard reports and folded sheets.
- Pre-printed routing lines: Five narrow-ruled columns give clear space to sign names and note departments, which helps track document flow.
- Hole punches for viewing: Punches let users verify documents inside without unfastening the envelope, speeding interdepartment routing.
Who It's For
These envelopes suit offices, schools, clinics, and any workplace that relies on physical interdepartmental documents and prefers a reusable solution to single-use mailers. Facilities that need clear routing records will appreciate the pre-printed lines and column layout for signatures and department names.
They are less appropriate for shipping long distances or for protecting highly sensitive materials from view, since the kraft material is not padded and the hole punches expose part of the contents. For external mailing or padded protection, choose a different mailer designed for shipping.

Frequently Asked Questions
Can these envelopes hold legal-size documents?
No. They are designed to store documents up to 10 in wide by 13 in long, so larger legal-size sheets would not fit flat.
Are the envelopes reusable?
Yes. The 28lb manila stock and string and button closure are intended for repeated use.
Do the hole punches compromise privacy?
The hole punches allow viewing of contents and may expose part of a document, so they are not ideal for fully confidential materials.
