Limited Edition - Key Cache X Lei Melendres

This collaboration has now closed. Sign up to our newsletter using the form at the foot of this page to be the first to know about our next limited run.

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."

Wedding presents - very well received

I ordered two key caches in black steel as a wedding gift for friends of mine and they went down an absolute treat. As always, Wingback does not disappoint!

Cache for cash

Great gift idea for friends & family. Customised with phone number or email it helps you get lost keys back and a decent ££ note in the cache is handy when your card or phone won’t work without internet. Nice heft, great design, simple, helpful

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.
