7 x 9 in White Rigid Mailers Kraft Cardboard Envelope - 200 Pack

Our review of these 7 x 9 in white rigid mailers finds them best suited for small businesses, artists and offices that ship flat paper goods and need a dependable, low-cost solution in bulk. The biggest reason to buy is quantity and consistency: 200 envelopes in one pack means fewer reorders and steady supply for routine mailing and storage. The mailers are rigid enough to protect prints and documents during transit while the peel-and-seal strip keeps packing quick and tool-free.

Key Features

• Bulk pack: 200 envelopes provide a steady supply for regular mailing, reducing the need to reorder frequently.
• Appropriate size: The 7 x 9 in dimension fits gift cards, photos, thin books and documents without excessive extra space.
• Rigid construction: Made from 146LB cover paper, the mailers resist bending and help keep contents flat during shipping.
• Self-adhesive closure: Built-in adhesive strips allow fast sealing with no tape or additional tools required, saving time when packing many items.
• Clean white finish: The bright white surface makes labeling, stamping or adding stickers straightforward for a neat presentation.

Who It's For

This pack works well for small shops that ship art prints, photos, certificates or slim books, and for offices that need a reliable envelope for documents and internal mail. Anyone who values a pre-sized, rigid option for flat media and wants enough quantity to cover frequent shipments will appreciate this product.

Those who need heavy cushioning for fragile three-dimensional items or waterproof protection should look at padded or poly mailers instead, since these cardboard envelopes are designed for flat, non-bulky items rather than fragile or wet-prone goods.

Pros & Cons

• Sturdy 146LB cover paper gives good rigidity to protect prints and documents.
• Peel-and-seal adhesive strip speeds packing and creates a clean, secure closure.
