Mailing Boxes are made for the postal and courier journey, built from corrugated cardboard to guard goods against knocks in transit. A well-sized mailer keeps the product still inside the box and presents a clean outer surface for labels and any branding.

Made to your custom size, the internal dimensions can be matched to your product so you carry less air and less filler. Sizing to the contents also helps keep the box within a postage band, which matters when the cost is repeated across every order. Noting your typical carrier and whether parcels are handled by machine also helps, since that can influence the board and closure the mailer needs.

Choosing the closure

Consider how the box is packed and whether it needs to open again for returns. A tuck or crash-lock base speeds hand packing, while a tape-down flap gives a firmer seal for heavier items; the right choice depends on your product and volume.

Specification points

  • Corrugated construction for transit protection
  • Custom internal size to reduce void and postage cost
  • Closure suited to packing speed and returns
  • Plain or printed outer for branding

Minimum order is 100 units. Send your product size and typical order profile, tell us whether the box needs to reopen for returns, and note any branding, and we will quote a mailer sized to keep your postage sensible.
