Custom Mailer Boxes That Do More Than Just Ship

Let’s face it — your mailer box is often the first real-world touchpoint a customer has with your brand. That’s a big moment. And with custom mailer boxes, you can make it count. Whether you’re packing curated gift sets or subscription kits, our mailer packaging is made to look sharp, hold strong, and feel like it came from someone who cares.

Find the Right Fit with Flexible Mailer Box Sizes?

No two products are exactly alike — and your packaging shouldn’t be either. We offer a wide range of mailer box sizes to fit everything from delicate accessories to heavy bundles. Need something precise? We’ll make it to spec.

Whether you need small branded boxes for boutique items or large bulk mailer boxes for eCommerce fulfilment, we’ll get the dimensions just right — no crushed corners, no oversized waste.

Custom Mailer Packaging That Speaks Your Brand

We don’t do boring. With our custom printed mailer boxes, you’re in full control of the look and feel. Go bold with full-colour artwork, or keep it clean and minimal — whatever fits your brand best.

Looking to impress your customers at first unboxing? Add:

  • Foil stamping, spot UV, or inside printing
  • Mailer box inserts for organised presentation
  • Seasonal designs or colour themes (think red mailer boxes for Christmas or promos)
  • Tear strips, magnetic closures, or other finishing touches

Our in-house team can help you map it all out — even if all you’ve got is a logo and a rough idea.

Printed Mailer Boxes That Are Easy on the Planet

People care about what their packaging’s made of — and honestly, so do we. That’s why we use stuff like FSC®-certified board, low-impact inks, and biodegradable materials when you need them. It looks good and it feels right.

Looking for something uncoated and recyclable? Go with kraft board. Want to balance protection and polish? We’ve got white or black lined corrugate options too. All functional, all sustainable, and all ready to ship without guilt.

Fast Turnaround, No Minimums, Total Flexibility

Whether you’re running a startup or a fast-moving brand, we get that time and flexibility matter. That’s why:

  • There’s no minimum order quantity on most styles
  • You can test short runs before going bulk
  • We ship across the UK with quick lead times
  • Need help with sizing or shipping-ready styles? Just ask — we’ll walk you through it
