mail box custom

A mail box custom order gives you a postal box built around your products, printed with your branding and sized to suit the postal service you use. Custom Postal Boxes manufactures mail box custom designs in house in Wolverhampton for UK businesses, with low minimum order quantities, free design support and free UK delivery.

Why sellers choose a mail box custom design

Standard boxes force products to fit whatever size happens to be on the shelf, which usually means extra padding, higher postage and a parcel that feels untidy when opened. A custom size reverses that problem. Less empty space means less movement in transit, fewer fillers to store, and a neater presentation.

Branding that travels with the parcel

Printed outer panels carry your logo and colours through sorting offices, delivery vans and doorsteps, so the parcel is recognised before it is opened. Inside print adds a second moment, with a greeting or handling notes, turning routine despatch packaging into part of the product experience.

Consistency across every order

Using one well designed box across a product range keeps packing simple for staff and makes every delivery look like it came from the same careful business. Consistent sizing also makes postage predictable.

Sizing a mail box custom box for the post

Measure your product with any protective wrap in place, then add a small allowance for padding on the sides that face knocks. Royal Mail explains its size bands on the Royal Mail guide to sending small parcels, where a small parcel can measure up to 45 centimetres long, 35 centimetres wide and 16 centimetres thick, with a maximum weight of 2 kilograms. The custom mailer boxes UK range is a useful starting point for most ecommerce orders.

Internal fit and protective padding

A snug internal fit holds the product steady, while loose contents slide, scuff and strike the walls of the box. Die cut inserts, tissue, paper void fill or a simple inner tray can separate bottles, jars and multi item sets. Test a packed sample by shaking it gently, then adjust the padding.

Closures that speed up packing

Self sealing strips close a box quickly and give a clean finish, while locking flaps add security for heavier contents. You can compare closure styles on the self seal mailer boxes page, and flat items such as clothing and printed goods may suit letterbox postal boxes that pass through the door without anyone waiting in.

Materials and print options for a mail box custom order

Corrugated cardboard is the usual choice for posted boxes because the fluted inner layer absorbs impacts and resists crushing when parcels are stacked. Kraft board suits handmade and refill brands, while white board carries bright artwork well. The cardboard mailer boxes page shows a widely used format, and print can run from a single colour logo to full colour artwork inside and out, with matt or gloss finishes to match your brand.

Choosing print coverage sensibly

A strong logo, a clear colour and one short message often read better at delivery distance than full coverage artwork. Keep labels and tape lines in mind when placing artwork. Free design support helps you balance impact, legibility and practical packing before anything goes to print.

Ordering your mail box custom packaging

FAQs about mail box custom

What does mail box custom mean?

Mail box custom describes a postal box made and printed to your own specification rather than bought as a plain standard size. You choose the dimensions, board, print and closure, so the box fits your products closely.

Can a mail box custom order carry my logo inside and outside?

Yes. Artwork can be printed on the outside for recognition during delivery and on the inside lid for a message, care notes or a thank you that appears when the box is opened. Free design support checks placement against folds and flaps before production begins.

Which board should I choose for posting products?

Corrugated cardboard suits most posted orders because its fluted layer cushions knocks and resists crushing in transit. Lighter goods may need only a single wall grade, while heavier or fragile shipments are safer in a stronger grade with fitted inserts.

How do I keep a custom mail box within a Royal Mail size band?

Measure the finished packed box on its longest sides and weigh it with all contents and padding included. Royal Mail small parcels allow up to 45 centimetres in length, 35 centimetres in width, 16 centimetres in thickness and 2 kilograms in weight, so sizing the box close to the product helps you stay within the band.

How do I get a price for a mail box custom order?

Pricing depends on size, material and quantity, so send your product dimensions, likely quantity and artwork idea through the contact page. You will receive a quote for your exact specification, with free design support and free UK delivery included on orders from Custom Postal Boxes.
