    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!

Perfect understated lasting gift...

I have bought two key caches for my nephews (age 20 and 17) and had their initials engraved on them. The key caches are not lightweight key rings -they are solid and incredibly well made and have the feeling of a lifelong lasting gift. I put £20 in each. I folded the £20 long ways into thirds then rolled as tight as possible then putting it in the lid of the cache before screwing the base on. The feedback from my eldest nephew (I bought his first for his 20th birthday) was so positive, he was absolutely delighted with it. He was so pleased, my sister called to suggest I get my younger nephew one too, when his birthday comes along.
