I have seen these KOH-I-NOOR pencils at a recent roofer and was instantly impressed. Ideally suited for the site to attach various labels. Very comfortable that the annoying sharpening belongs in the "cheap" wood pencils the past - once was not a knife at hand, you stand with the thick construction pencils made of wood already on the hose. A robust and comfortable tool for the craftsman - 5 stars.
