This School Smart flexible plastic ruler set is marked to 1/16 inches on one side and metric on the other. Thin, flexible, and see-through plastic makes our bendable rulers durable and easy to use. A flex design allows the durable metric ruler to be easily bent without breaking for use in tight corners or at odd angles. Each scale ruler has clearly black outlined inch and centimeter marks for consistent measurements each time. Kids and adults love the user-friendly 12 inch measuring tool.
