In the days of texting and email, it's highly unlikely that you'll get enough post to fill it, but this mail storage unit from Rockett St George could adapt itself to all sorts of storage. It's got 15 pigeon holes, 4 letter shelves and 6 drawers in which you could stash away your bits and pieces and at 81cm high and 80cm wide it could sit atop another work unit or desk.
It's described as 'vintaged' but it isn't exactly clear what that involves, presumably a bit of doctoring to make it look older than it actually is. However, at £180 per unit it might be tempting to try and pick up a similar looking original for yourself instead.
