Review: Good replacement for Itoya NPR-5 refill - I can’t comment on how long the ink lasts, but this refill fits in my pen that originally used a Itoya NPR-5 rollerball refill. 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.
