    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.

    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.

Perfect lovely compact tools

Great job from the beginning, from ordering to sending it home. Everything went very conscientiously. Not disappointed, I am very pleased with the quality, compassion, lightness, strength. Thanks to the authors of the idea and its producers.

Lovely products. Special.

Style and substance

There are many ways to carry a little bit of emergency cash in an increasingly cashless society. The Wingback key cache is just a little bit stylish than most. Laser engraved with a return phone number (just in case as it is on my minimal carry carry).

Beautifully Made.

I have just received the key cache in brass and a custom moleskin note book cover. Both are exceptionally well made and personalised to me so feel very special. Keep up the great work Wingback team.

Hated it, made my front pocket chunkier if anything.

Way too expensive, you have to make it yourself, makes your front pocket carry another thing, I much prefer a carabiner which doesn’t work well with this either when you carry house keys and a car key fob, when I asked if they could help me they chose not to and rather me return the item and get a refund instead which took money out of my pocket, extremely unhappy.

Hi Pablo,

It's a shame the key cache wasn't to your taste - you asked for help with an international return which I talked you through and then refunded your order once it had arrived back at the workshop. We don't offer free returns, either internationally or domestically in the case that someone changes their mind.

Best of luck finding a more suitable addition to your keys.
