that's true if you like invisible ink.

Great black ink pens.

Generic, typical business blue ink, completely unmatched to the blue on the outside.

The ink flows smoothly and it doesn't smear.

The ink doesn't leak and they last a long time.

Even when you think they have dried up, all you have to do is rub the pen back and forth between your hands and it warms the ink, allowing it to have a fresh start

The ink flows really well and I never have difficulty getting a nice consistent glide
