HMM Rule/One



The HMM Rule/One is a real game-changer. Originally launched on Kickstarter, it was an immediate success. The HMM Project design team have since refined the concept subtly.

Rule/One is a compact ruler/bookmark/tablet stylus/ballpoint pen combination that not only looks fantastic but is really well thought out from a practical perspective. The stylus and lanyard attachments screw on to the ruler and are interchangeable.

The ruler provides measurements in both metric and imperial standards and holds the pen in place when not in use through an ingenious magnetic system. Thanks to its teardrop profile, it can be used as a compact bookmark, which will fit the standard-sized Traveler's Notebook very nicely. 

The lanyard attachment allows you to carry it round your neck when you are on the move.
