*** LIMITED RUN OF 25 ***

For a limited run only, the Key Cache, our minimal keyring stash for your emergency cash, is back in a matte Black Steel Oxide finish. A tricky process, black oxide bonds chemically with the surface of the metal to leave a majestic gun metal finish.

Designed in London and made in the UK, the Key Cache is built to enhance and complement your everyday carry, while discreetly adding functionality. It neatly fits onto your keyring while containing a secure compartment to store banknotes and contact details in case your keys go missing. 

Having emergency cash tucked away will spare your blushes when you leave home without your wallet. It could even save your bacon on your travels – a backup $100 note can get you out of a lot of tricky situations.

 Plus, tucking a little "if found" note inside will help track down your keys if you misplace them (and the reward is already in there).

Video instructions on how to fold the notes to fit inside the Key Cache can be found below.

You can match your Black Steel Key Cache with the black steel oxide fasteners on our range of Cash and Travel Wallets.
