"The show proved that Mystery Jersey King is both authentic and high-quality, and the credibility of Dragons' Den gave me the confidence to fully believe in myself as an entrepreneur."
Alex StreetCo-Founder, Mystery Jersey King
"Alex is such a character, and his enthusiasm lit up the room the moment he walked in. With an endless supply of unique shirts that sport and fashion fans adore, Mystery Jersey King has global appeal."

Everything to Know About
Everything to Know About
Mystery Football Shirts.
01
What Is a Mystery Football Shirt?
A mystery football shirt is a genuine football jersey selected at random and delivered to your door. You choose your size and budget, tell us any teams or leagues to avoid, and we send you a surprise shirt from clubs across the globe.
The mystery element makes every order an event in itself. The unboxing is half the fun. Our mystery football shirts come from leagues in Spain, Germany, Italy, South America, the USA and beyond, spanning current seasons and classic retro kits.
02
The Perfect Football Gift
A mystery shirt box is one of the most original football gifts you can buy. It works for any fan regardless of which club they support, because the whole point is the surprise. Perfect for birthdays, Christmas, Father's Day and graduations.
For groups, our share boxes let everyone open a different shirt together. A brilliant idea for stag dos, hen dos, office parties and family gatherings. Choose from 3, 5 or 10-shirt bundles, all delivered in one box.
03
The Monthly Mystery Shirt Subscription
Our monthly subscription is the most popular way to build a genuine football shirt collection. Pay a fixed monthly fee, save 15%, and receive a brand new mystery shirt every month. No duplicates, no fakes, no faff.
Available for men, women and kids, with prices from £25.49 a month. Skip a month or cancel completely whenever you want. No contracts, no penalties.
04
Are Mystery Football Shirts Worth It?
If you love football shirts, yes. The retail price of a current-season Premier League shirt can exceed £70. Our mystery boxes start from £32 and every shirt is genuine, brand new, and from a real licensed club or national team.
The real value is in the discovery. You might receive a third kit from a lower-league side in Mexico, a classic retro from a 1990s Champions League team, or a current shirt from a league you've never followed. See what's available today.
