0.5mm Orenznero mechanical pencil, black. Pentel Orenz Nero Write with the lead protected by the pipe! Equipped with the "Orenz System" that prevents lead breakage, and an "automatic lead advance mechanism" that advances the lead every time the pen tip is lifted! The tip pipe slides in accordance with the lead wear, protecting the lead while writing, so even the extra-fine lead won't break. Furthermore, it is equipped with a mechanism that automatically advances the lead every time the pen tip is lifted from the paper, allowing you to continue writing until the remaining lead becomes short with just the first one-click knock. - Model: Orenznero 0.5 - Color: Black - Accessories: Package - Type: Mechanical Pencil Thank you for viewing.
