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."

More than just a keyring accessory.

This little key cache is a great solution for an issue I have found myself with on a few occasions. Such as being at the till only to find the store doesn't accept card, the late night taxis when your money has already been spent. No more getting caught out and rushing around to find a cashpoint!

After experiencing the inch perfect mechanical pen, the machining on this again exceeds my expectations. Wingback delivers products at a level above anything else I have experienced. Realising an issue and coming up with a solution, while turning it into a quality & eye-catching piece is mastery. Even the keyring which comes with the cache is made with quality, with the subtle branding and quote 'FOR YOUR JOURNEY' adding character to my set of keys.

I opted for the Lei Melendres edition as the fun little doodle character helps break the cache from a perfectly machined piece of metal into a piece of keyring art! The character is unique and fun, while being subtle at the flat end. I found a slight issue in that the doodle was off centre, not enough to notice at a quick glance but as I examined the piece I discovered it favoured one side.

Overall this Key Cache helps provide a solution to what can otherwise be embarrassing and difficult situations. The machining and material quality of this piece cannot be better and deserves 5 stars. However, I have knocked it down to 4 (4.5 if it was an option) due to a slight off-centering with the doddle.

Hey Reece, thanks for taking the time to leave your review. Send us an email about the etching of the illustration and we can look at getting that fixed for you. Cheers, Charlie
