SULLIVANS INTERNATIONAL-The Cutting Edge Frosted Ruler. Keeps you sharp so you never lose your EDGE! The diamond powder edge maintains the sharpness of your rotary blade as it spins. Full see- through NON SKID frosting keeps the ruler from sliding and makes it light enough to see your fabric through it. A unique red grid system highlights the 1/2" markings, use both lines to square up blocks or to cut squares effortlessly. Large numbers make for easy visibility that never blends into the fabric. Very light 1/8" markings do not distract when using the most common 1/4" markings. This package contains one 4-1/2x4-1/2in frosted ruler. Imported.
