The BIC Xtra-Precision Mechanical Pencil is designed for precision and accuracy. These pencils come with fine 0.5mm leads that create sharp, clean lines, making them ideal for any type of careful, neat writing, detailed sketches, or delicate illustrations. The smooth-writing #2 lead is perfect for tests, does not smudge, and erases cleanly to help keep your work looking tidy. The lead advances quickly with a single click and never needs to be sharpened, saving you time. The metallic barrels add just the right amount of shimmer to your desktop.
