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."

Great for secret stuff

Just what I needed

The Key cache is just brilliant. I was looking for something I could use on the key ring of my motorbike keys. Somewhere to stash the note for the refreshments on the long day trip. No need for the bulky wallet sitting uncomfortably in my pocket. The design is elegent yet rugged which suits my purpose brilliantly and it has already been a talking point on the coffee stop on my last ride out. Outstanding :)

Craftsmanship Counts

Love my Key Loop and Key Cache from Wingback. Beautifully machined and with a great finish that’s going to age well. Can’t wait to see the mechanical pencil!

Key Cache saved my night!

I was away for a business trip, went out with some friends but left my wallet in the hotel. After a moment of panic I remembered I had the key cache attached to my keyring. The £20 stashed away got a taxi back to my hotel and a massive reduction of blood pressure.

A couple of tips:
- Keep the key cache attached to an object that’s on your person at all times. Go for the most ubiquitous object. Keychains are great, although you might also attach it to a belt loop, a backpack, or an EDC pouch.
- Depending on what you attach it to, think about the attachment method. A ring is great for a keychain but a carabiner is better if you’re going to attach it to your jeans, or a paracord lanyard if you’re going to put it in your bag.
- I think all the metal options look great, but the Black Steel version I have feels luxurious, doesn’t scratch, and it doesn’t draw attention to itself (which is crucial).

I bought this as a 50th gift for my brother, he loved it, the workmanship and feel of it really appealed to him.
