These are generally smooth refills, though quality control lets a few rough ones
out here and there. The plastic body and thin diameter means they run out of
ink quickly, but such is the nature of the beast. If one is looking for a pen
with larger writing capacity, he or she can pretty much say the same think about
all multi-pen refills. Overall, these are great little refills, though I think
the Zebra D-1 0.5mm gel refills are the best, and noticeably smoother.
