Quality Park 9 x 12 Clasp Envelopes 100
Reviews
Product description
These clasp envelopes make organizing, filing or mailing documents straightforward, offering sturdy construction and a reusable metal clasp for frequent handling. If you need protective, larger-format envelopes for reports or paperwork, these 9 x 12 clasp envelopes for mailing documents combine capacity and simple closure for office and home use.
Key Points

Designed to hold letter-size or unfolded 8.5 x 11 pages with room for inserts, these envelopes are made from brown kraft paper that resists tearing during transport. The metal clasp keeps contents secure while still allowing easy opening and resealing, which is useful when you need to add or remove documents frequently. They come in a box of 100, making them convenient for bulk filing, mailrooms or small businesses that process paperwork on a regular basis.


They are practical for archiving client files, delivering printed proposals, or sending invoices without folding. The kraft surface is writable with ballpoint pens and labels adhere well, so identification and indexing are simple. Consider that kraft paper shows marks more easily than coated stock, so avoid heavy moisture exposure and rough handling to preserve appearance.

Usage Recommendations
For mailing, pair the envelopes with appropriate postage and a rigid mailer if contents require extra protection. When storing in filing cabinets, arrange vertically to limit pressure on the clasp and reduce bending of contents. If you plan to reuse the envelopes, avoid folding the flap repeatedly and keep the clasp clean to ensure consistent closure. For aesthetic projects or presentations, consider using label strips or printed inserts to maintain a professional look.

Positive Aspects
The combination of a deeply gummed flap and a metal clasp gives two closure options for different needs. The heavier 28 lb kraft paper has more substance than standard copy paper, which helps protect documents and maintain envelope shape during handling. Economically packaged in boxes of 100, these envelopes reduce the need for frequent restocking and are easy to store on a shelf or in an office supply area.
A minor limitation to note is that the brown kraft finish can be more susceptible to visible scuffs than smoother coated papers, according to typical kraft characteristics. Also, while the clasp is durable for repeated use, repeated heavy loading may eventually strain the closure, so avoid overfilling beyond the envelope capacity.
