Perfect for students, artists, and designers, the Mono Graph Zero features sturdy Tombow construction and a comfortably grippy knurled metal grip section. But its most exciting feature is its super-fine twist eraser. Just 2.3 mm wide, it #39;s ideal for erasing small mistakes in drawings or math equations without disrupting the rest of your work. And with nearly a full inch of usable length, it still lasts longer than a typical drafting pencil eraser. Features: - Long, super-fine 2.3 mm twist eraser for precise erasing. - Sturdy plastic barrel. - Knurled metal grip section for controlled grip and low center of gravity. - 4 mm fixed lead pipe for good visibility of the writing surface and easy use with a template or straightedge. - To refill the pencil lead, grip the push button and pull it out with your fingers to expose the lead storage tube. Add the refill leads, then insert the push button back into place. ===== Untuk refill penghapus dapat dibeli pada link berikut : https://www.tokopedia.com/lix/tombow-mono-graph-zero-eraser-refill-pack-isi-3-er-mgu
