This generic refill produces a nice thin black line with roughly the same ink flow as the original refill.The price is right. If the ink fails too quickly, I will update, but I’m pleased with my purchase. ### ⭐⭐⭐⭐⭐ Perfect *by on Reviewed in the United States October 6, 2024* These 4.37 inch Rollerball Pen Refills offer great value for anyone looking to keep their favorite pens going strong.
