Description

These #10 security envelopes from Quality Park feature a convenient self-seal closure and side-seam construction for reliable, everyday business correspondence. The security tinting on the interior ensures confidential information remains private during mailing, while the single window design eliminates the need for addressing envelopes separately—simply align your letterhead or invoice and the address shows through clearly. Each envelope measures the standard business size of 4-1/8" x 9-1/2", perfect for folding 8.5" x 11" documents into thirds.

Ideal for accounting departments, small businesses, and administrative offices that handle sensitive documents like invoices, statements, financial records, and confidential correspondence. The self-seal strip saves time compared to traditional gummed envelopes—just peel and press for a secure seal without moisture. The durable construction and professional white exterior ensure your business communications arrive looking polished and professional.

This bulk pack provides excellent value for high-volume mailing needs while maintaining consistent quality across all your business communications. The side-seam design offers superior strength and a clean, professional appearance that reflects well on your organization.
