Mailer Boxes With Inserts UK

About our box

Mailer Boxes With Inserts, made to your size

When a box holds more than one item, or anything fragile, an insert makes all the difference. Our mailer boxes with inserts are built around your products, with die-cut card, corrugated or foam inserts that keep each piece in its own space from the warehouse to the customer’s table.

Why choose our mailer Boxes With Inserts

Inserts stop products from knocking together, remove the need for bubble wrap or paper fill and turn a loose collection of items into a neat, deliberate presentation. That matters for gift sets, subscription boxes and anything with glass.

Questions about Mailer Boxes With Inserts

Which insert material should I choose?

Card and corrugated inserts are the most recyclable and work for most products. Foam gives the most protection for glass and electronics. We will recommend the best option for your items.

Can the insert be printed?

Yes. Card inserts can be printed in full colour, which is a good place for instructions or a thank-you message.
