Key Cache - Brass

A minimal, machined, solid brass stash for your vital details and emergency cash. Designed in London. Made in the UK.

The key cache is designed 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 can be found below.
