Black Ink Refill for Tombow MONO Graph Lite Ballpoint Pen

I received the ballpoint pen as a freebie in a VIP pack. Then I received a second freebie when I ordered refills and the blue pen. These ball point pens are the best I've found and I've been searching a long time. The point hold its width and doesn't become gummy, or expand its width. The ink dries quikly. I now own all the colors in the 0.5 and 0.38 sizes. I've given them as gifts to an author friend who has been searching for a fine line ballpoint pen. I LOVE these pens and have several refills (even though the ink lasts forever) so that I don't run out. Wow! thank you, Tombow!

This pen is so easy to work with and makes a fine line. I like this pen better than Micron (a fave) because the tips don't wear down.
