Stainless steel rules are perfect measuring and ruling devices for home, school and office. Increments and numerals are precision-etched into the polished steel surface and filled with permanent black ink for long life and easy readability. The flexible tempered steel will not crimp or nick, making these rules ideal for use in the most demading situations such as job site work and cutting operations. The cork backing provides non-slip stability and gives the rule lift for smear- and bleed-free ruling with any type of pen. No sharp edges and rounded corners make steel rules safe for even the youngest users.
