There are 3 different size rulers in the package: 6 inch, 12 inch, and 18 inch, each with slip-resistant cork backing. The rulers feature clear inch and metric measurements, enabling quick and accurate measurements and straight line drawing. They are suitable for precise measuring tasks and help improve work efficiency. Made of high-quality metal, these rulers are rust-resistant and durable. The metal construction allows slight flexibility for measuring curved surfaces without breaking. Smooth, flat edges with right-angled corners provide reliable accuracy. The cork backing helps prevent slipping, keeping the rulers stable during use. These rulers also help prevent ink from bleeding underneath. Equipped with hanging holes for easy storage and portability, they save space when not in use.
