10 x 13 Open End Envelopes Avocado Green - Flat Document Mailers

In this review of the 10 x 13 Open End Envelopes the bottom line is simple: these are a practical, heavyweight solution for anyone who needs to mail flat, bulky documents without folding. The reviewer found they work best for business mailings, annual reports and tax forms where presentation and protection matter. The envelopes arrive in a pack of 500 and the peel-and-press closure speeds up batching; overall the standout is their sturdy 70lb. text weight paper that keeps contents flat during handling.

Key Features

• Open end design: The 10 x 13 open end orientation makes it easy to slide in catalogs and booklets without bending them, reducing handling time.
• Peel and press flap: The peel-and-press adhesive gives a secure, tamper-resistant seal and speeds up repetitive mailings compared with manual moistening.
• 70lb. text paper: A heavier stock that adds rigidity and protection for brochures, W-2 forms and other important documents in transit.
• Avocado color: A distinctive tone that helps corporate and direct mail stand out in a stack while still appearing professional.
• Pack of 500: A bulk quantity that suits offices and mailing campaigns, reducing the need for frequent reordering.
• Printable compatibility: Usable on off-set and digital presses and some home printers, making them adaptable for branded mailings.

Who It's For

These envelopes are aimed at offices, accounting departments and businesses that send catalogs, annual reports, W-2 / 1099 forms or promotional booklets and need to preserve document condition. The combination of a larger 10 x 13 opening and heavy 70lb. paper is ideal for flat but bulky materials that must not be folded.

Shoppers who want exact color matching or very small quantities should look elsewhere; the avocado tone receives mixed feedback and the pack of 500 is geared toward medium to large volume mailing rather than one-off personal use.
