MORE DETAIL

Wingback are known for their heavily engineered approach when it comes to metal components. Materials are aerospace-grade and the processes employed use an incredibly fine level of precision machining, producing hardware and accessories that scream quality.

These key caches demonstrate that precision engineering. They feature a hermetically sealed compartment that's water tight, so can be used to safely stash cash or notes for those emergency times your card doesn't work, you lose your phone (or keys) or somebody steals your wallet. Just roll a banknote up in the housing and forget it's there until you really need it.

Aside from this handy compartment, the keyring itself is really high quality, using high-grade European brass expertly milled in Birmingham. Unlike your usual thin, cheap keyrings, this one will last decades, sporting Wingback's inspirational "For Your Journey" motto laser-engraved around the loop.

The textured cross hatching creates another little perk–a tactile surface that's great for those who like to fiddle with their keys when they're out and about.
