I am disappointed in the color of this refill. Unlike the previous reviewer I
did not expect a ball point to write as smooth or as vibrant as a gel ink but I
did have high hopes that Zebra would still put out a decent product. The color
is very weak, almost impossible to read on bright white Clairfontaine Vellum
paper. The other aspects are fine, consistent line, no skipping, everything you
have come to expect from Zebra Ballpoint refills.
