Still stuck?

Email info@mysteryjerseyking.com and we'll get back to you within 24 hours.

Yes. Every shirt we send is 100% genuine. We work with trusted suppliers and manufacturers worldwide, and every new source goes through our rigorous screening process before a single shirt reaches our customers. No fakes. Ever.

The Men's Mystery Box is £37.99 as a one-off, or £32.29 a month on subscription.

UK delivery is £2.99 on one-off orders and free for subscribers.

Yes. At checkout you can tell us which teams, leagues or colours you'd like us to avoid. UK customers automatically receive a shirt from outside the UK unless you specifically request otherwise.

A brand new mystery football shirt lands on your doorstep every single month for a fixed monthly fee. Subscribers save 15% compared to ordering one-off and get free delivery on every box. The first box ships within 3 to 5 days of subscribing, and your subscription then renews on the same date each month.

Yes. You can skip a month or cancel completely at any time through your account dashboard. No contracts, no penalties, no extra charges. Pause when you want, return when you want.

UK orders typically arrive within 3 to 5 business days. International orders take between 4 and 15 working days depending on your location.

Yes. We've shipped to over 150 countries. EU customers benefit from our IOSS registration, meaning customs charges are handled at checkout so your parcel clears without delays. Orders over €150 may attract import duty on arrival depending on your country.

Yes. You can return your order within 14 days of delivery. Full details are on our Shipping and Returns page, or email info@mysteryjerseyking.com and we'll help.

Sizing varies widely between countries and brands. A UK small and an Asian small can be very different. If we feel a size up will give you a better fit, we'll make that call and include a note in your box. If anything needs exchanging, email info@mysteryjerseyking.com and we'll help.

No. Our mystery boxes don't include classic retro kits. If you're after a specific retro shirt, browse our retro football shirts collection, sold separately.

Yes. Co-founder Alex Street pitched Mystery Jersey King on Series 22 of BBC Dragons' Den in January 2025. Sara Davies MBE invested £50,000 for a 15% stake. We're the only mystery football shirt brand to ever appear on the show.

Everything to know about mystery football shirts.

  1. What is it?
  2. Gifts
  3. Subscription
  4. Worth it?

A mystery football shirt is a genuine football jersey selected at random and delivered to your door. You choose your size, 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, from famous clubs to hidden gems you've never heard of.

Christmas pick

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.

Our monthly subscription is the most popular way to build a genuine football shirt collection. Pay a fixed monthly fee, save 15%, get free delivery and receive a brand new mystery shirt every month. No duplicates, no fakes, no faff.

The Men's box is £32.29 a month and the Kids box is from £21.24 a month. Skip a month or cancel completely whenever you want. No contracts, no penalties.

If you love football shirts, yes. The retail price of a current-season Premier League shirt can exceed £70. Our mystery boxes start from £24.99 as a one-off, or £21.24 a month on subscription, and every shirt is genuine, brand new, and from a real 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 shirt from one of Europe's biggest clubs, or a team from a league you've never followed. See what's available today. Want a specific classic instead? Browse our retro football shirts.
