the best ink for Pentel...,
February 20, 2010
the best ink for Pentel brush pen (I used this ink for some other brush pens at
my own risk) and it is waterprooof and very dark which is not easy to find when
using brushes.
I wish Pentel would develop a grey version (same waterpoof type) of this ink to
be used with Pentel brush pen (they have the larger color petel brushes but they
are not waterproof). That would be cool for drawing.
