The Rule/One by HMM Project is the sort of creation that designers covet: it’s a supremely convenient pen-ruler combination that’s lightweight and compact enough to act as a bookmark for your notebook. It’s made with only five pieces of milled aluminum that’s anodized in black, ultimately resulting in a unique droplet shape that’s compatible with a series of interchangeable heads. They include a ballpoint, stylus and lanyard, making the Rule/One a simple solution for multiple modes, whether you’re using paper or a tablet, or even if you’re on the go.
