An ideal companion to your notebook, this mechanical pencil will keep your writing crisp. With a design dating back to the 1920s, it works using a twist mechanism that opens the chuck at the tip, pushing the 0.7mm HB graphite lead forward; when the chuck is closed, it holds the graphite in place. An internal chamber holds several refills that are automatically pushed to use one after the other. The refillable Drehgriffel pencil comes in four colours that match Leuchtturm1917 notebooks. A design object to behold, it has a geometric hexagonal barrel and a pleasing weightiness that adds to its retro quality.
