Mystery Shirt In A Box – A Custom Printed Boxes Case Study

Mystery Shirt In A Box is a fast-growing ecommerce brand built around excitement, surprise and premium presentation. The concept is simple but powerful: customers receive a mystery football shirt from anywhere in the world, beautifully presented and ready to impress from the moment it arrives. With a strong social media presence and a loyal customer base, Mystery Shirt In A Box has become particularly synonymous with peak retail moments such as Black Friday, where demand surges and customer expectations are at their highest.


For a brand built on experience as much as product, packaging plays a critical role. The box is not just a transit solution, it is the first physical touchpoint between the brand and the customer. For Mystery Shirt In A Box, this made the reliability, quality and finish of their custom printed boxes non‑negotiable.

The Challenge


Just weeks before Black Friday, the brand’s single biggest sales event of the year, Mystery Shirt In A Box faced a major operational crisis. Their existing box manufacturer unexpectedly failed to meet the agreed production timeline. What had been confirmed as a pre‑Black Friday delivery was suddenly pushed back to after Christmas.


The impact was immediate and severe:


  • A requirement for 30,000 custom printed boxes with no existing supply
  • A fixed Black Friday deadline that could not move
  • A risk of delayed orders, damaged brand reputation and lost revenue
  • Very limited time to source an alternative supplier with capacity

At the busiest time of year for the packaging industry, many manufacturers were already operating at full capacity. With time running out, the situation required speed, flexibility and a partner willing to go above and beyond.

The Turning Point


In a last‑ditch effort, Mystery Shirt In A Box publicly reached out via LinkedIn, asking for help from the packaging and manufacturing community. The post quickly gained attention, highlighting both the urgency of the situation and the reality many fast growing ecommerce brands face when supply chains fail.


Lil Packaging saw the post and immediately recognised both the challenge and the opportunity to support a brand at a critical moment.

The Lil Packaging Solution


Despite being in the middle of our own peak production period, Lil Packaging mobilised quickly. Our priority was clear: assess feasibility fast, communicate honestly, and deliver a solution that protected the client’s Black Friday campaign.

Our approach included:


  • Immediate specification review
  • Rapid capacity assessment
  • Fast‑tracked artwork and approvals to avoid unnecessary delays
  • Clear, realistic timelines with constant communication throughout production

Working closely with Mystery Shirt In A Box, we confirmed that the full order of 30,000 custom printed boxes could be produced and delivered in time, without compromising on quality.

The Lil AELL03 Large Letter, custom printed boxes were manufactured to specification, including the die‑cut design, ensuring the unboxing experience remained premium while also being practical for fulfilment teams during peak volume.

Why Custom Printed Boxes Mattered


For Mystery Shirt In A Box, these weren’t just boxes, they were a vital part of the customer experience. Custom printed boxes:


  • Reinforced brand recognition during a high‑volume sales period
  • Elevated the perceived value of the product inside
  • Created a consistent, shareable unboxing experience
  • Helped maintain trust during the busiest time of year

In fast paced ecommerce environments, generic or last‑minute packaging can undermine even the strongest product offering. Delivering fully branded, custom printed boxes ensured Mystery Shirt In A Box could meet customer expectations without compromise.

The Result

Lil Packaging successfully delivered all 30,000 custom printed boxes in time for Black Friday, allowing Mystery Shirt In A Box to:


  • Fulfil orders without delay
  • Maintain brand presentation during peak trading
  • Protect customer satisfaction and repeat purchase potential
  • Turn a potential crisis into a success story

What could have been a damaging supply chain failure instead became an example of what’s possible with the right packaging partner.

This project highlights the value of using a responsive, experienced packaging manufacturer, not just a supplier. At Lil Packaging, we understand that packaging is often the final piece of the puzzle, but when it fails, the consequences can be significant.
