From what I'm told, The Hole Measuring Tape is nothing new, but I like the idea of a measuring tape that lets you make circles and lines with ease.
The Hole Measuring Tape is pretty innovative with many facets to it. It allows you to draw straight lines and circles with precision. Although not clarifies, I am assuming the tape is retractable and offers measures in more than one measuring system. Simple and functional, I'm sure you designers will love it!
