High-quality, latex-free erasers remove lead easily and cleanly with very little pressure. No smudges, no paper tears and no ghosting. Erase caps fit on most wood-case pencils. Block-style erasers with protective sleeves are perfect for getting into little corners or erasing large areas quickly. Erasers won't crack or harden with age, remaining soft and ready to use. Hi-Polymer eraser set includes four white cap erasers, one small block eraser and one large block eraser.
