This ruler is specially designed for ink drawings. With beveled sides and a precision distribution in mm, this ruler is perfect for accurate measurements. The zero point is in the middle of one side, making it easy to start measurements. Made from crystal clear acrylic with a green center track, this ruler is not only functional, but also aesthetically attractive. The 20 and 30 cm versions are equipped with a rubber strip and acrylic strip to prevent the ruler from tilting and shifting during use. The 40 and 50 cm versions have two rubber strips for extra stability.
