Frequently asked questions

What does Royal Mail PiP mean?

PiP stands for Pricing in Proportion. Royal Mail charges by the parcel's format (Large Letter, Small Parcel, Medium Parcel) as well as weight, so a box built to the right PiP size can lower your postage cost.

How do I know which PiP size I need?

Match the box format to your item: Large Letter for slim items, Small Parcel for everyday orders, Medium Parcel for bulkier goods. Internal dimensions are on each product page; allow 10-20mm tolerance.

Can PiP boxes be printed with my logo?

Yes. We print your full-colour logo and artwork in the defined print areas on each box. We cannot print full-wrap or guarantee an exact Pantone match.

Why order boxes sized to Royal Mail PiP?

Using a box built to the correct PiP format helps keep your parcel in the lowest suitable postage band, which can noticeably reduce your shipping costs.

What colours and materials are available?

Brown kraft or white, made from recyclable E-flute corrugated board, FSC approved where applicable.

What is the minimum order and turnaround?

Minimums are low and shown per product page, with dispatch as quick as the next working day when your proof is approved by 12pm.

Can I order a sample first?

Yes. A printed sample, with the fee refunded on a matching order, or a blank sample for a few pence lets you confirm the size and print.
