10 x 13 Open End Envelopes - Smoke Gray, Pack of 1000

Our review of these 10 x 13 open end envelopes finds them a practical choice for businesses and individuals who need to send flat or bulky documents without folding. The main reason to buy is their combination of sturdy 80lb. text stock and a convenient peel and press flap that keeps contents secure while allowing quick preparation of large mailings. Customers who value consistent color and reliable construction will appreciate these envelopes for catalogs, reports, and tax forms where presentation and protection matter.

Key Features

• Open end format: Lets you insert pamphlets, magazines, and booklets flat so materials arrive undamaged and look professional.
• Peel and press closure: Provides a fast, tamper-resistant seal for high-volume mailings and saves time compared with moist-flap envelopes.
• 80lb. text stock: Offers a stiff, durable feel that resists tearing and protects bulky contents during transit.
• Smoke gray color: Gives a professional neutral look that works well for corporate mailings, invoices, and tax documents.
• Printable compatible: Works on off-set and digital presses and on some home printers for easy addressing and branding.
• Pack of 1000: Supplies large mail projects affordably so businesses can prepare catalogs and annual reports without frequent reordering.

Who It's For

These envelopes are aimed at offices, accounting firms, publishers, and mailing houses that send catalogs, annual reports, brochures, W-2 and 1099 forms, or other flat bulky materials. The sturdy 80lb. text and open end design are especially useful during tax season and for corporate mailings that must arrive flat and intact.

Shoppers who need fewer than a thousand envelopes, or who require specialty materials like padded mailers or colored window envelopes, should consider alternatives better matched to low-volume needs or different presentation requirements.
