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.

### ⭐ Works ok for a while, then bleeds all over the pages
*by L***O on July 14, 2026*

They leak heavily if not moving fast enough. At first it worked ok, then it starts to let too much ink out. I included pictures of what happens. Now it's leaking all over my pen. Piece of crap
