This is a Pilot G-3 ballpoint pen. The ink flow is not very good. Other thicknesses and colors are also available. There is still stock, so I can increase the quantity. *Even items listed as "new and unused" may have scratches, scuffs, or stains due to long-term storage. We appreciate your understanding. Regarding unopened items, we have not confirmed their operation, so please understand this beforehand. Especially in the case of ballpoint pens, the ink may not flow. If you would like to check the ink, please comment. We cannot guarantee the ink. Please check my profile before purchasing. Many of the items for sale are stationery items such as writing instruments. Please feel free to take a look at my other listings. All items are available for immediate purchase. If you would like to check the condition of the item, please comment. We also accept requests for additional images. We will offer a discount for purchases of sets or bulk purchase requests. Thank you for your consideration.
