This aluminum ruler is sleek and lightweight making it perfect for storing and bringing around in a pen case. It measures up to 30cm when extended but for measuring smaller items, it can be folded and used comfortably in its half size. The durable aluminum material allows you to use the ruler as a straight edge with a blade or cutter without damaging the ruler itself, and because the measurement markings are laser engraved, they won't fade over time. You can even use this ruler as a protractor to measure angles using the angle measurements on the ruler's hinged central axis. On one side, the numerical scale starts from right from the edge of the ruler, making it easy to measure along a wall.
