Helpful Answers
About Custom Mailer Box — Frequently Asked Questions
Can I order just one mailer box sample?
Yes, we can send a sample so you can check size, board feel and folding. However, production starts from MOQ 100 boxes because real tooling is needed to test crease memory, lid friction and fit tolerance. This shows the true performance of the finished box.
Are mailer boxes simple to assemble during packing?
Yes, they fold along pressed channels so the board keeps shape easily. Panels lock square without force and corners stay neat, helping staff pack mailer boxes for ecommerce quickly and consistently. When you order, our team will also record a simple assembly video so your staff can follow the exact folding method.
How long does delivery take within the UK?
Timing depends on print coverage and drying time, as heavy ink needs longer curing to prevent scuff. Our normal turnaround time is 10 to 14 working days. After dispatch, courier routes and weather can affect arrival, however cartons stay flat and colour remains stable in transit.
What finish will customers notice when opening the parcel?
Customers notice touch and colour first. Matt feels soft while gloss looks deeper. On printed mailer boxes we control rub resistance so branded mailer boxes remain clean after handling.
Can I print inside and outside of the box?
Yes, as long as artwork stays within safe zones. We keep graphics away from folds so ink does not crack, which works well for packaging for online orders that include messages inside.
How do I choose the correct box size?
Measure the wrapped product, not the bare item. You can also send us the exact product size and we will design the best fitting box around it. A small gap keeps the lid closing flat without pressure and improves stacking strength during storage and shipping.
Will the boxes protect products during courier transit?
Yes, when board grade matches product weight. We test compression and corner strength so mailer box packaging handles sorting belts and stacking during delivery.
