Aimoh 9x12 self-seal brown kraft envelopes are sturdy 28lb manilla mailers with a peel-and-seal closure, sold in a box of 100 for secure large-document mailing.

These Aimoh 9 x 12 catalog envelopes are built from heavy 28lb kraft paper to protect magazines, brochures, documents and promotional pieces during transit. The pre-applied peel-and-seal adhesive strip creates a quick, reliable closure without licking or tape, while the natural brown finish provides privacy and a professional, low-cost look. Each package contains 100 envelopes sized to accept unfolded 8.5 x 11 sheets plus extras, making them practical for offices, small businesses, and home use.

How do these envelopes protect large documents in the mail?

The 28lb kraft construction is thicker than standard envelope stock, resisting tearing, punctures and postal wear. The woven paper texture adds strength and helps keep contents private during handling.

• 28lb heavy-duty kraft paper for tear resistance
• Full-width self-seal strip for a secure closure
• Size fits unfolded 8.5 x 11 documents, catalogs, brochures
• Natural brown color conceals contents and looks professional

How fast and reliable is the self-seal closure?

The peel-and-seal adhesive eliminates the need for moisture or tape: peel off the liner and press the flap to close. The adhesive is formulated for a firm bond across the full flap width so envelopes stay shut during normal postal handling.

• Pre-applied peel-and-seal strip—no licking required
• Full-width adhesive for consistent sealing
• Designed to hold brochures and thicker contents securely

Can I address or customize these envelopes for business mailings?

• Printable surface for laser and inkjet label use
• Writable by hand with most pens and markers
