This fantastic tool is a protractor and ruler all-in-one! Durable, convenient, and portable, this aluminum multi-ruler is 30cm long when fully extended, and smoothly folds into itself with a click. The central rotator features marks every 15 degrees, making it easy to measure angles. Marks are laser-engraved and easy to read. Sleek and professional while still remaining utilitarian, its no wonder this ruler won the 2013 Good Design Award.
There are no inches on this ruler, only centimeters. 15.9 x 2.9 cm when folded.
