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. 

For this limited edition collaboration, we teamed up with Manila-based illustrator Lei Melendres, bringing one of his “We Are Infinite” doodle characters to life on the base of the Key Cache.

Laser engraved in brass or stainless steel, this collaboration is a celebration of Lei’s sprawling creations, defined by repetition, pattern, monsters, animals, unimaginable creatures and the unknown.

Lei Melendres is a freelance illustrator and the head of Doodle Art Enthusiasts, the Philippines’ largest doodling community. His inimitable artwork has graced books, magazines, murals and galleries around the world. Lei describes his infinite doodle style as conveying the intensity of endless details and elements interacting together to form a scene of art.

Commenting on the design, Lei says, “I think of the different characters I draw in my artwork as the people we have met throughout our lives, who have influenced us physically, mentally, emotionally and spiritually."

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.

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, hello@wingback.co.uk.

Really enjoy the Key Cache. I´ll use it as keyring pendant for the car keys. I´ll keep a small note for emergency cases in the key chache. Altough I have in my my pockets with other keys it shows no signs of usage. Undestructible! Having said this I must admit that the key ring I ordered with the key chache is showing massive signs of usage. The black colour flake off at the edges. This is not a good deal at all.
