Frequently asked questions
What sizes and colours are the large letter postal boxes?
Twelve sizes from 147mm x 138mm x 20mm up to 430mm x 219mm x 23mm (width x depth x height), in brown kraft or white E-flute, printed outside, inside or both.
Can I print my own branding, and is there a minimum order?
Yes. Every box is printed in full colour with your logo or design, and there is no minimum order - bulk pricing is applied automatically as quantities increase. A one-off setup fee of £49.95 applies to orders under £100 (exc VAT) and is waived on re-orders of the same product using the same artwork. You always approve a printed proof before we produce your full order.
What material are large letter postal boxes made from?
Corrugated kraft E-flute cardboard - slim but rigid and protective - FSC certified with 60% to 90% recycled content and recyclable.
What are large letter postal boxes best for?
Their shallow depth is designed to fit Royal Mail Large Letter guidelines, helping you post flat items at a lower postage rate while keeping them protected and branded.
How fast is delivery, and can I order a sample first?
Production begins once you approve your proof. Choose your speed at checkout: Standard Express Production (6-10 business days, free on orders of £70 and over, otherwise £10), Priority Production (3-5 business days, £50) or Priority+ Production (1-2 business days, £80). Approve your proof by 12:00 midday on a working day and we despatch the same day. Those rates cover mainland UK; Northern Ireland, Guernsey, Jersey and the Isle of Man are priced separately and cannot use Priority+. You can order a printed sample first to check the print and material before committing to a full run.
