Brown Rigid Mailers 13 x 18 in Pack of 10 - Flat Cardboard Photo

In this review the focus is on the ABC PACK & SUPPLY Brown Rigid Mailers, a set of 10 flat cardboard envelopes measuring 13 x 18 in. These mailers are aimed at small businesses, artists, and anyone who ships flat items like prints or framed photos and wants a low-cost, sturdy option. The single biggest reason to buy is their rigid, tear-resistant 550 GSM construction that keeps contents flat in transit while offering a simple self-adhesive closure for quick packing.

Key Features

• Rigid 550 GSM cardboard: Provides firm support to keep photos, prints, and flat artwork from bending during handling and shipping.
• 13 x 18 in size: Fits common flat items such as 11 x 14 framed pieces and larger prints with room to spare for light padding.
• Self-adhesive closure with tear-off strip: Ensures a fast, reliable seal that reduces the risk of accidental opening in transit.
• Writable kraft surface: Allows for easy labeling, personalization, or note addition directly on the mailer without extra labels.
• Pack of 10: Offers a small bulk quantity useful for occasional shippers, artists selling limited runs, or office use.
• Recyclable material: Kraft cardboard construction makes these envelopes an easy choice for more sustainable shipping decisions.

Who It's For

This product is best for independent artists, photographers, crafters, and small sellers who ship flat media and want a balance of protection and affordability. The rigid board is particularly suited to mailing prints, unframed artwork, postcards, and brochures that must remain flat.

Those who need absolute protection for high-value framed works or heavy-duty weatherproofing should look elsewhere or add extra padding and waterproof outer packing, since these are cardboard mailers intended primarily to prevent bending rather than full crate-level protection.

Pros & Cons

Pros

• Sturdy 550 GSM construction that resists bending for most flat items.
• Convenient self-adhesive closure with a tear-off strip for quick sealing.
• Writable kraft surface makes addressing and custom notes simple.
• Good value for a pack of 10, suitable for small runs and occasional shipping.

Cons

• Some customers report mixed bendability results, so extremely delicate or high-value pieces may need added reinforcement.
• Adhesive strength received mixed feedback, so additional tape may be desired for very long shipments.
