No. 2 mechanical pencils offer a unique, two-in-one eraser so you can erase twice as many mistakes. Once you wear out one eraser, simply pop the eraser out, flip it and insert the second, included eraser on the other side. Both erasers are smudge-resistant and latex-free. Quick Flip Mechanical Pencils also offer strong, No. 2 leads (0.5mm) that are perfect for standardized tests and comfort grips for precise control. Lead and eraser are refillable.
