Shipping Mailers for Small Items

These white corrugated mailers measure 4 3/8" x 4 3/8" x 2 1/2" and come in a pack of 50. They suit businesses sending small, flat products such as electronics accessories, cosmetics or jewellery. The rigid fluted construction protects contents from bending and impact during transit. Buyers who need larger boxes or padded envelopes should look elsewhere.

Lightweight Protection and Storage

The single-wall corrugated board keeps each mailer light while resisting crushing in normal postal handling. Flat storage reduces warehouse space until the mailers are folded into shape. No special equipment is required for assembly or sealing. The white exterior provides a clean surface for labels or branding stamps.

Pack Quantity Defines Order Size

Each purchase delivers exactly 50 mailers in one package. This fixed count determines how many shipments you can prepare before reordering. Orders of $75 or more ship free from the manufacturer. Operations with higher daily volume will need multiple packs or a different supplier.

Questions about this item

How do I assemble and seal these 4 3/8" x 4 3/8" x 2 1/2" corrugated mailers without crushing the contents?

Fold along the scored lines to form the box, place items inside, then close the flaps and apply packing tape across the centre seam and edges; avoid over-compressing the walls before taping.

When should I replace a mailer instead of reusing it for another shipment?

Replace any mailer that shows crushed corners, torn flaps, punctures, or moisture damage, as the corrugated structure loses rigidity and may not protect the next parcel.

At what load does the corrugated wall typically buckle under sustained stacking?

The single-wall corrugated construction will buckle first under heavy stacked weight, so limit pallet height and avoid placing concentrated loads on the centre of the lid.
