But one brand is on a mission to resurrect it, casting aside tacky plastic in favour of brushed aluminium in the process. The Aluminium Case Company is that brand, and its cases are not to be trifled with – somehow managing to look eye-catching, elegant, and like they could probably survive a nuclear bomb.

They're unique, too: you can choose from models influenced by aviation pioneer R.J. Mitchell or Malcolm Sayor, creator of the Jaguar E-Type; or you can go bespoke. Starting at north of £4,000 for a case, they're not cheap – but for something genuinely timeless, eminently beautiful and pretty much indestructible, that's a steal. The briefcase is dead; long live the briefcase.
