Rollbe Click Ruler
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
The latest version of the Rollbe circular ruler now makes a click sound for every full rotation, making it easier to tally measurements. It also now comes in black, with the units laser-engraved for easier reading. It’s still available in 4″/10cm or 8″/20cm.
