Pentel Mechanical Pencil Orenz Nero 0.5mm

This pen has a spring loaded metal nib sheathe that is required for the auto lead extension, but because of that the metal sheathe often rubs against the paper. Do not buy if you write at a shallow angle like a fountain pen or have a heavy hand. Moreover in-spite of the grip looking fantastic on paper, once your hands get oily or sweaty it’s very annoying to use. I quite enjoy it for taking short notes, and can use it in a pinch for longer writing sessions when nothing else is around and this pencil is always on hand. Only use pentel refill leads and other brand refills could cause the auto lead extension system to malfunction due to the micro/nanometer difference is lead diameter and composition. This is a “precision” instrument.
