The ruler also functions as a protractor and a compass. The circular swivel joint between the two arms of the ruler is marked from 0° to 180° in 15° increments, and the ruler snaps into place at each interval. Additionally, each arm has a small hole every 1 cm that is perfectly sized for the tip of a mechanical pencil. You can use the holes to precisely space dots along a line or swivel the arm while holding the other arm in place to draw an arc.
About Midori
MIDORI is a Japanese stationery brand that began as a producer of writing paper and envelopes in 1950. Since then, they have evolved into a comprehensive stationery brand with a wide range of design-focused products that enrich and add color to enhance expression with paper items. Their name Midori means “green” in Japanese and is inspired partly by the lush green blades of grass and weeds growing in the burnt fields in postwar Japan.
