The black rulers and protractor are made of clear acrylic and have a slip-resistant backing, making it easy to measure and draw precisely. The millimeter (or degree) markings are easy to read and they change height every 5 mm (or 5 degrees), further facilitating reading measurements. Each black ruler has measurements that begin at the very edge of the ruler. This is convenient for measuring things when an extra gap at the end of the ruler may get in the way. The right triangle rulers are also useful for drawing parallel and perpendicular lines.
The yellow mini ruler is great for quickly drawing a lot of short straight lines. It's flexible, which is useful for drawing or measuring in cramped spaces where notebook rings or other obstacles might normally get in the way. It also has circles ranging from 3 to 10 mm in diameter, for drawing small circles which are difficult to draw with a compass.
The case is slim and sturdy, and the lid stays open at a vertical or tilted position. Four small stickers for writing your name are also included.
