FAQ

Mailer box questions on structure, board, inserts, MOQ and samples

What is the difference between a mailer box and a shipping carton?

A mailer box usually has a self-locking structure and customer-facing unboxing surface, while a shipping carton is mainly built for bulk transport and stacking.

Can mailer boxes include a tear strip or zipper opening?

Yes. Tear-strip and zipper mailer options can be reviewed when the box size, board, closure, and opening direction are confirmed.

Should inserts be quoted with mailer boxes?

Yes when product movement, presentation, accessory count, or damage risk affects the final layout. Inserts should be approved with the mailer sample.

Can mailer boxes have inside print?

Yes. Inside print, messages, color panels, and branded unboxing details can be reviewed when the dieline and artwork are available.

What MOQ and lead time apply to custom mailer boxes?

MOQ is 200 pcs per size for each style, and one order can mix several sizes and styles. Samples typically take about 7 days after confirmed specs, and production typically takes 15–30 working days after approval. See what the 200 pcs minimum applies to and what moves sample and production lead time.

Are custom mailer boxes worth it for a small brand?

They are worth considering when the box is part of the customer experience, a subscription, PR sendout, or repeat DTC shipment. For very early validation, a stock mailer plus label may be enough before custom print.

Can a mailer box ship directly without an outer carton?

Often yes for light to medium DTC goods, but it depends on product weight, fragility, carrier handling, and whether surface scuffs are acceptable. Fragile or premium goods may still need an outer carton or insert.

What size should I send for a custom mailer box?

Send the internal L x W x H needed for the product and insert, not just the outside of an existing box. Also send product weight, quantity, print coverage, sample need, and destination. The six inputs a packaging quote needs are listed on one page.

Which options create a better unboxing experience?

Inside print, tear strip, branded insert, tissue fit, spot UV, foil, and a clean tuck closure can improve unboxing. Keep the first sample focused so the structure and color are approved before adding more effects.

Can I start with a low pilot run for custom mailers?

Yes, but the unit price will usually be higher because setup and sample costs are spread over fewer pieces. Use the pilot to validate size, fit, print, and customer response before a larger run.
