Uni-ball SA-7CN Ballpoint Pen Refill - 0.7 mm - Red

This is a fun refill! The line is super broad, easily rivaling a liquid ink rollerball style pen in line width and color saturation. Very smooth, though I've experienced minor skipping when too little pressure is applied - just the weight of your hand is generally sufficient though. I think it is so broad that sometimes the ballpoint isn't completely re-coated in ink when spun in the tip which causes this minor skipping. I would definitely recommend this one to a fountain or rollerball pen fan who is looking for a decent ballpoint.

Nice and smooth for a ballpoint and doesn't skip. The color is almost on the purple side when compared with other blue inks. Slightly on the finer side of a 1.0mm.
