Magnetic Flexible 18" Ruler

Is that Length Flexible?

Remember those slap bracelets that swept the nation a few years back? This 18" long x 3/4” wide easy-to-read ruler is sort of like those in that it stays bent and then snaps open again, but nothing like those in that this is a tool, not a fashion accessory. Or is it? Until you decide on that, consider that, tool-wise, it has magnets on the end to keep itself shut, but also to attach it to dry-erase boards or anything metal. Has standard 1/16" markings with clear lines and large digits.
