    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. For video instructions on how to fold the notes to fit inside, click here.

  • Metal: Aerospace grade stainless steel from Europe, CNC machined in Birmingham, UK. Tungsten carbide carbon finish applied in Cambridge, 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 Black Steel key cache retains all the precision and corrosion-resistant qualities of stainless steel, while the tungsten carbide finish increases the surface hardness 9x. Any marks it picks up from regular use should be easily wiped away. However, the surface is scratch resistant, not scratch proof. Anything harder than the surface (diamond, some ceramics) or really aggressive use will be able to scratch it, but most items you would carry in your pocket shouldn't. Just remember to carry your diamonds in a separate pocket!

Father’s Day gift

I purchased the steel key cache as a gift for my partner for Father’s Day from our son and daughter! He loved that I had it engraved with emergency ice cream fund. Was a personal touch. Great gift and great service

RW (Stockport, GB)
Key Cache - Brass

Really great item. The quality of materials and attention to detail are second to none. Your customer services (Megan) are great too - I had also bought a Winston wallet (under a separate order) - Megan was very helpful in ensuring both items shipped together.

Tim (Tottenham, GB)
Key Cache

I've previously submitted a review for the black key cache which never made it on to the review site. Looks lovely but by the time it was assembled onto the key ring there was already 'flaking' and loss of the black colour cover. Not sure this is particularly resistant.

Hi Tim,

Thanks for getting in touch, your previous review is indeed on our sight with a detailed reply from me. I explain why we can't coat the two items in the same finish and why we then include a steel key ring with every black steel purchase.

Take a look as I believe this will clear things up for you. If you have any further questions please get in contact with me via email,
