Product identity

Quality Park 63778 envelopes are 10 x 13 inch interoffice mailers built for confidential documents. The gummed flap seals securely and requires a signature across the closure for tamper evidence. Offices handling expense reports or sensitive paperwork use them to control access.

Sustained use

The 28 lb Gray Kraft stock resists tearing during repeated handling and stacking in mail carts. Red and blue printed warnings remain legible after multiple trips through internal routing. Gum adhesive holds firm without reactivation in normal office humidity.

Practical limits

The 10 x 13 format fits standard letter pages folded once but not unfolded A4 or legal sheets. Capacity is limited to the 100 envelopes supplied in each box. No moisture barrier or tracking features are included.

Questions about this item

How much does a full box of 100 envelopes weigh for daily handling?

A full box of 100 envelopes made from 28 lb Gray Kraft stock is light enough for easy daily handling and transport between departments.

What do I need on hand to seal these envelopes securely?

The gummed flap requires only moisture to activate the adhesive, so no tape, glue sticks or sealing machines are needed.

Will the red and blue confidential markings stay clear if I write on the envelope with a standard ballpoint pen?

Yes, the printed red pattern and blue "Personal and Confidential" messages remain legible under normal ballpoint or rollerball writing.
