This is a 0.5mm mechanical pencil from Mitsubishi. I am also selling other colors. *Please note that even items listed as new and unused may have scratches, scuffs, or dirt due to long-term storage. We appreciate purchases from those who understand this. For unopened items, we cannot confirm their operation, so please understand this in advance. Especially for ballpoint pens, the ink may not flow. If you wish to check the ink, please leave a comment. We cannot guarantee the ink. Before purchasing, please check my profile. Many of my listings are stationery items such as writing instruments. Please feel free to browse my other listings. All items are available for immediate purchase. If you wish to check the condition of an item, please leave a comment. I can also add more images. I offer discounts for purchases of sets or bundled items. Thank you for your consideration.
