A ruler's traditionally a straightforward thing, but that doesn't mean it has to be boring. These pretty pieces from Monkey Business give you a measuring edge when you need it, and a city skyline stencil when you're feeling playful.
The Skyline Ruler is available in seven cityscapes: London, Paris, NYC, Berlin, Amsterdam, Toronto, and Jerusalem. Each $9 plastic piece has a full 20cm ruler on the bottom edge (yes, even the NYC ruler is in metric).
There's something fun about a well-made stencil, and buying one that's also a ruler feels slightly less superfluous. Is it functional? Sure! Especially if you happen to have the type of job where you need to sketch a highly accurate skyline at a moment's notice. [Monkey Business]
