Flat Mailer Capacity

This pack contains one hundred flat mailers designed for shipping documents and flat items. The white envelopes suit office mailrooms, e-commerce sellers and anyone sending paperwork that must stay crease-free. Each unit is new and ready for immediate use.

One Hundred Unit Pack

A quantity of 100 mailers covers regular despatch volumes without frequent reordering. The pack handles daily posting runs and small fulfilment batches comfortably. Very high-volume operations will exhaust the supply quickly and need larger cartons.

Flat Mailer Dimensions

The 9-3/4 by 12-1/4 inch format fits standard letter and A4 pages without folding. Thick catalogues or rigid objects exceed the flat profile and require a different mailer type. The size matches common postal large-letter allowances.

Questions about this item

Will these 9-3/4" x 12-1/4" white flat mailers fit in the same storage bin as my older padded envelopes?

The flat mailers measure 9-3/4" x 12-1/4" and come in a pack of 100, so they stack neatly alongside padded envelopes of similar or larger dimensions without needing extra shelf space.

How can I confirm the pack contains the full 100 white flat mailers after opening the box?

Count the mailers; the package quantity is 100, and each mailer is a white flat mailer sized 9-3/4" x 12-1/4", so a quick count verifies the correct amount.

What comes in the box and do I need to buy anything else to start shipping?

The box contains 100 white flat mailers measuring 9-3/4" x 12-1/4"; no additional items are required to use them for mailing.
