I've used zebra blue...
, February 5, 2014
I've used zebra blue black inks in the past and found them to be exceptionally
good. The color was almost black with a hint of blue making them a unique
personal trade mark of sorts. These refills however were truly a
disappointment. The color was almost "turquoise" and the refills ink supply
runs out much quicker. Unfortunately, I was unable to return them within the
allotted time frame so am stuck with them.
