This is a discontinued Pentel "ENERGEL" ballpoint pen. BLN13 0.35mm (Extra Fine) Pentel / JAPAN Dye/Water-based Gel Ink Needle Point Black Ink This is deadstock, so it is an unused item that has not been in anyone's hands! I'm not sure of the exact age, but I think it's in good condition for its age. It is usable at this time, but please understand that it is a retro item from that era before purchasing m(_ _)m ★This is the last one remaining. ☆I am also listing (and planning to list) other discontinued writing instruments. #cottonrose_pen ********************************* ☆I also list Showa-era retro stationery and novelty stationery items other than writing instruments. #cottonrose_retro If you purchase multiple items together, I may be able to offer a small discount depending on the shipping costs, so please feel free to ask (^-^) ※As this item is also listed on other flea market apps, I will prioritize the buyer who purchases it first. Also, I may suddenly withdraw the listing due to this.
