STAEDTLER Ruler Triangular Ruler Drafting Set Ink Edge Mars 564 26 TN

Like Lumograph's high-quality pencils for drafting, it has a 2mm lead that provides smooth writing with little loss of writing. A vertical groove is carved into the lead, which engages with the clutch mechanism of the lead holder to prevent retraction during writing and prevent the lead from rotating while using a lead sharpener. In addition, the hardness display is printed in 6 places on the core body, making it easy to check the hardness even if the core is short.
