Midori Aluminum Ruler -30cm

Two rulers in one, connected by a pivot screw that lets you measure angles in 15-degree increments. Closed, it works as a standard 30cm straight edge. Open it up and the two 15cm arms become a protractor-style angle guide, useful for layouts, sketching, or any time you need more than just a straight line. The markings are laser-engraved directly into the aluminum so they won't fade or wear off with regular use.

Matte black, solid, and made in Japan. The kind of desk tool that looks good sitting out and actually earns its place there.
