Designed to eliminate the confusion and strain of reading your typical ruler. On the SAE side, the 1/4, 1/8 and 1/16 increments appear in a vivid white on a high-contrast, vibrantly colored background; and on the metric side, the millimeter increments appear in a vivid white on a high-contrast black background, making this ruler easier to use than others in the market. The ruler's non-glare surface also helps you take a quick and easy measurement. Ruler works great as a straight edge, too.
