Product Identity

Business Source 4645 No. 10 envelopes deliver a self-sealing solution for high-volume mailing tasks. The 500-count box suits offices that process invoices, statements or direct-mail pieces on a daily basis.

Build and Daily Use

Each 24 lb sheet carries an interior security tint that blocks readable text when held to light. The double-flap construction protects the adhesive until you lift the lower flap and press, removing the need for moistener bottles or tape.

Included Extras

The package contains only the envelopes themselves; no additional software, labels or sealing tools are supplied. This keeps the workflow simple — load the stack, print addresses and seal without extra steps.
