For those times you need help reading the printed page, the Magna-Ruler doubles the height of letters. It lies flat on the page and magnifies two lines of type at a time without any need to focus. The 10" overall length offers an 8" scale in both inches and centimeters, making it very useful with tabulated data. The ruler also serves as a linear guide, so there's no need to squint and struggle.
