We spotted something similar to this at Paperchase last year. if you missed out, you can always opt for the equally cool retro toy robot Christmas decoration set at Fab.
The title pretty much tells the story. A set of four glass ornaments shaped like the kind of clunky robots you would find in a 1950s or '60s b-movie. Far more stylish than a glass ball on a tree, that's for sure.
You can pick up a set on Fab right now, with the price for four decorations at £10.
