Category: Mailer Boxes

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.

Buyer’s guide — before you ask for a quote

Honest answers to help you specify this box. Where a detail depends on your job, we say so rather than guess.

What size should I order, and can you make it to my dimensions?
This box is made to your own size. Measure your product's length, width and height and allow a little clearance for easy packing, then send us those internal dimensions. Unsure of the best fit? Confirm with our team and we can advise or arrange a sample.
Which material and board weight is right for my product?
The material shown for this product is Corrugated cardboard. Other boards and weights may also suit your product depending on how much protection and rigidity you need. Tell us what you are packing and we can recommend a suitable option — Confirm with our team if you would like to compare.
What printing and finishing options can I ask about?
When you enquire it helps to tell us how many print colours you need (or whether you have Pantone references) and whether you want a finish such as matt or gloss lamination, soft-touch, spot UV, foil or embossing. Availability and cost of each finish depend on your box and quantity, so Confirm with our team to check what is possible for this product.
How should I prepare my artwork, and will I see a proof?
Supply print-ready artwork as a vector PDF or AI file with fonts outlined, images at 300dpi and any brand colours specified. If you do not yet have a dieline, ask us for one for this box so your design lines up with the cut and fold. We share a proof for you to approve before anything is printed — Confirm with our team for current proofing timescales and file requirements.
How is the price worked out?
£3.55 per unit as currently listed — your exact price is confirmed in a free written quote. Price depends on your size, quantity, board, number of print colours and any special finishes — larger quantities usually lower the unit cost.
What is the minimum order and how do I place an order?
The listed minimum order for this product is 100 units. To order, send us your size, quantity, material and finish for a free written quote, approve your proof, then we move to production. If you need a different quantity, Confirm with our team.
How far ahead should I plan for delivery?
Production starts once you approve your proof, so plan your deadline back from there and allow time for artwork, proofing and delivery. Lead times vary by product, quantity and finish and are not fixed on this page — Confirm with our team for a realistic timescale for your order before you commit to a date.
Are there any compliance or safety points I should raise?
This product sits in our Mailer Boxes range. If your packaging has legal or safety requirements — for example food-contact suitability, child-resistant or tamper-evident features, or specific recycling and labelling marks — tell us at enquiry stage so we can confirm what is achievable for this box. We will not claim a certification or standard we cannot evidence, so confirm with our team about your specific requirements.
