Direct answer: For literature mailers, match length, width, depth, closure style, material, color, and pack quantity. Depth is the field most buyers miss.
A literature mailer is not the same as a flat envelope. The right mailer depends on whether you are shipping one document, a catalog stack, a sample kit, or a dimensional packet.

FAQ
What is the most important literature mailer field?
Depth is often the deciding field because the footprint may fit letter-size content while the stacked kit is too thick.
When should I use a box instead of a literature mailer?
Use a corrugated box when the item needs cushioning, has fragile edges, or does not sit flat in the mailer.
Are literature mailers usually reusable?
Some corrugated mailers can support returns, but reuse depends on closure damage and carrier handling.
