From Faber-Castell, the Perfection 7058 features a firm, white eraser core suitable for various forms of liquid, water-based & ballpoint inks. Contained in a wooden eco-pencil barrel, this eraser is able to be sharpened to a fine point using only a standard sharpener, for pin-point precision & erasing of extremely fine details. Faber-Castell erasers are made using a balanced plastic mixture, ensuring soft, smear-free erasing every time. Also available is the Perfection 7056 eraser, featuring a softer, pink core for use with graphite, colour pencils & copies.
