Rollbe is a new rolling compact ruler that can easily measure almost any surface. Flat, curved, rolling, corners, whatever it is, you can measure it with the Rollbe. It comes in two size options, 4 in. and 10 cm. A rolling curve ruler isn’t a brand new thing, but one that looks this sharp and is made of stainless steel with a brass handle. You can even get a leather key chain pouch to keep it handy. It’s only a bit bigger than a coin so won’t take up much space. You can still get the early bird pricing of about $16 if you’re quick.
