Rigid 6x8 in Photo Mailers 350 Pieces - Thick 350GSM Protection

Our review of these rigid photo mailers finds them best suited to small businesses, photographers, and anyone who ships flat prints or documents and needs consistent protection. The single biggest reason to buy is the pack size combined with a thick 350GSM kraft construction that resists bending and keeps prints flat during transit. Delivery came as a bulk bundle of 350 self adhesive 6 x 8 in envelopes, and the strong peel-and-seal strip makes packing quick and reliable for repetitive shipping or archival storage.

Key Features

• 350 pieces: A large pack ensures you have enough mailers for frequent shipping, reducing the need to reorder frequently and saving time.
• 6 x 8 in size: The dimensions fit most photographs, small prints, postcards, and flat documents without excessive folding or trimming.
• 350GSM kraft material: Thickened cardboard offers stiffness that helps prevent photos and documents from bending or creasing in transit.
• Self adhesive seal: The upgraded adhesive strip creates a secure, long lasting closure that keeps contents inside and limits risk of loss.
• Professional appearance: The crisp brown kraft finish gives a clean look suitable for clients, galleries, or office shipments while still allowing labeling or stamping.
• Multiuse protection: These mailers are suitable for photos, certificates, CDs, small booklets, and similar flat media that need rigid support.

Who It's For

These mailers are aimed at small business owners, photographers, print sellers, and mail-order operations that ship high volumes of flat items and need a reliable, low-cost protective solution. The bulk 350 count is particularly useful for those with consistent outgoing orders or who prep mail frequently.

Shoppers who need padded cushioning, waterproofing, or very large formats should look elsewhere; these rigid mailers provide stiffness and surface protection but are not padded or sized for large posters or bulky items.
