Double Window #8 Business Envelope — 3.63 x 8.63, White, 500/Box

Streamline every professional mailing with a purpose-built Double Window Envelope crafted for efficiency and clarity. The dual windows are precisely positioned to reveal the essential address information from your document, so you can print once and mail with confidence—no extra labels or fiddling required.

Sized at 3.63 x 8.63 inches, this #8 envelope is ideal for common business documents like invoices, statements, and remittance notices. The crisp white stock preserves a clean, professional look that showcases your branding and contact details through the window openings, while helping recipients read your information at a glance.

• Dual-window design: Two windows align with standard billing layouts, letting the recipient address and any necessary return information show through from a single printed document.
• 500 per box: A bulk supply that supports regular billing cycles, payroll runs, and client communications without constant reordering.
• Professional white finish: A clean, understated appearance that keeps your messages legible and your brand looking sharp.
• Versatile use cases: Invoices, statements, bills, notices, and other business correspondence that benefit from a simple, windowed presentation.
• Consistent window alignment: Designed to provide predictable results across batches, reducing guesswork in your mail preparation process.

Ideal for whom

Perfect for small to medium-sized businesses, accounts payable teams, freelancers issuing invoices, utilities, property managers, and service providers who mail frequent statements and notices. If you send documents that already include the recipient’s address in a fixed position, these envelopes help you present that information clearly with minimal handling.

Why choose these envelopes over basic options

Compared to single-window or non-window envelopes, the Double Window #8 design minimizes the need for extra labeling and manual adjustments. You print your document once, fold it to size, and the windows reveal the necessary details directly to the recipient—faster processing, fewer errors, and a more professional impression.

Practical tips for best results

• Print or print-run your address block on your document so it sits within the windows when folded to 3.63 x 8.63 inches.
• Keep documents flat and aligned before inserting into the envelope to ensure clean window exposure.
• Store envelopes in a cool, dry place to maintain consistency in folding and presentation over time.

Add these Double Window #8 envelopes to your mailing toolkit and enjoy a streamlined, professional approach to business correspondence. 500-ready envelopes per box help you stay stocked for ongoing invoices, statements, and notices—without interrupting your workflow.
