    Cache (kash) [noun]

    1. a hidden place for provisions, valuables, treasure – as used by explorers or adventurers

    2. a secure place of storage

    The Wingback Key Cache is designed to enhance and complement your everyday carry, while discreetly adding functionality. 

It neatly clips onto your keyring and contains a secure compartment to store banknotes and an “if found” note in case your keys go missing. Having emergency cash tucked away will spare your blushes if you forget 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. Machined from a solid bar of aerospace-grade stainless steel, the Key Cache has been designed to last for decades, not months.

  • Metal: Aerospace grade stainless steel from Europe, CNC machined in Birmingham, UK.

    Keyring: As above, (included with your Key Cache).

    Sleeve: Oeko-Tex double thickness cotton sleeve from Poland, Europe.

    Finish: Laser engraved, assembled by hand and packaged in London, UK.

  • Dimensions: 40.50mm x 13.6mm diameter (outer), 31mm x 10mm diameter (inner)

    Capacity: Fits GBP, EURO, USD and every other note we have tested (the maximum size we have tried is 160mm x 82mm)

    Engraving: All inscriptions are in capital letters and run around the base of the Key Cache

    Considerations: The stainless steel Key Cache won’t require additional care. It will withstand almost anything you can throw at it without losing a shade of its original glory.

Just a perfect thing

Love it! From the packaging to the service and finally to the product, there is a small final turn when you are closing it up that is so satisfying! Sorry can’t recommend it to friends, it’s mine and I don’t want them to know where u got it. Thanks!

Great little accessory!

Brought the stainless steel key cache, very elegant & smaller than you’ll expect. Had a tough time working a £20 note inside, so do wonder how easy it’ll be to remove when needed? Nonetheless, this is definitely worth the price if you value having cash on you without the need for a wallet.

As usual - perfect quality

Thank you . Great and classy

Great Company

You made the transaction easy and delivered exactly what you promised. I love my new brass key ring with the little key cache

Brass Key Cache

This arrived very well packed and on-time. When I opened the box I was stunned by the accuracy of the machining and the look and feel of the Key Cache. Out of the box it is a five out of five. However, I spent a bit of time with some Autosol and elbow grease and it's even better now as brass takes a great polish, just waiting for it to patina now. You can easily get multiple Tenners or Twenties into it (Not tried a Fifty but I'm sure it would fit).
I'm a bit of a Cu and Ti nut so I would really like the Key Cache in those metals too.
Anyway - You should buy some these as they are fantastic!

I'm not on the payroll incidentally.
