Mar Mar Co is one of the cutest shops in London – fact. Did you know its moniker is an amalgamation of owners Mark and Mariannes names? See, cute! This modular wire shelf is an instant classic. You can choose from yellow, blue, green, black or red wire and mix and match as you go or just stick to your favourite hue. The wooden shelf is also white on one side, black on the other – the options are literally limitless. They look great stacked in a line from floor to ceiling.
