This KOH-I-NOOR Extra Hard Eraser 6642 is a cylindrical rubber eraser with a distinctive blue hue, primarily designed as a high-precision, abrasive correction tool for specialised art, drafting, and office applications.
It has a long, round cylindrical shape and measures 75 mm in length with a 12 mm diameter. It is made from eco-friendly natural rubber produced completely free of plastic materials and phthalates.
Because of its extra-hard, abrasive composition, this eraser is engineered to cleanly rub out mediums that standard soft erasers cannot easily remove. It is highly effective for scraping away tough ink marks from heavy paper or drafting film, and for making strong corrections to stubborn materials like pastels, charcoal, and hard pencil lead. The rigid, circular cross-section allows artists to maintain sharp edges for tight detail work or lifting specific highlights.
