Authenticity

We source our items directly from brands and retailers to bring you a curated selection of the best possible boxes.
Sustainability
Sustainability
Over 30% of clothes made never get sold, this issue is particularly prominent in the football shirt industry. Brands will not be caught short on their stocks, and so will regularly over-produce to ensure needs are met. At the end of the season, this can result in huge amounts of extra stock no longer needed, and most of this will end up in landfill.
Instead of these overproduced products going into landfill or struggling to be sold, we buy stock through our innovative buying process meaning there is no waste and our customers have an awesome experience.
Sizing
Sizing
Each manufacturer uses a unique size guide, so we diligently work to categorize our shirts into the available size brackets. If you find yourself between sizes, we recommend choosing the larger option, as most football shirts are made with a slimmer fit compared to other regular shirts.










HOW IT WORKS
-
The Problem
To avoid running out, brands often overproduce — but once the season ends, that extra stock is no longer needed. Most of it ends up in landfill, contributing to the 2 million tonnes of textiles discarded in Europe each year.
-
The Solution
We partner with some of the biggest retailers and football clubs in the world — buying their excess stock through our innovative sourcing model. Instead of going to landfill or sitting unsold, these products get a second life, with nothing wasted.
-
The Result
Our customers receive a quality football shirt at a fraction of the retail price — it makes a great gift and supports a more sustainable way to shop.

Hi, I’m Matty, Founder at Mystery BOXD.
Massive football fan, passionate about sustainability, and on a mission to tackle football’s hidden waste problem.
Each season, clubs over-order kit — and millions of shirts go unworn. In Europe alone, up to 3.6 million items are wasted every year. That didn’t sit right with me.
So I started Mystery BOXD — a circular retail concept that rescues unsold stock and turns it into surprise mystery boxes that fans love.
Since launching two years ago, we’ve grown to a community of 30,000 customers and now partner with some of the biggest football clubs and retailers in the world — including my own club, BWFC.
It’s affordable, exciting, and better for the planet.
Thank you so much for your continued support.

How to wash products?
Most products include a label or tag outlining the ideal conditions for laundering. In many cases, and particularly for older items, we encourage you to disregard these instructions, as requirements change as a product and its materials age.
Wash cool, inside-out on a hand-wash cycle if available, and for particularly delicate items, hand wash only.
Under no circumstances should fabric conditioner be used as this may remove print and patches from shirts. Similarly, avoid ironing, tumble drying items or mixing colours as this can cause irreversible damage.
We cannot be held responsible for any damage caused when washing if these guidelines are not followed.
