Ballpoint ink Refills Sepia-Brown

Long time I have search for a Sepia-Brown Ballpoint ink !

Have found by AuthenticExpressions .

the brand "MONTEVERDE".

The problem: You must buy a expensive ballpoint pen

for minimum 60 Dollars :(

After visiting some shops, long thinking and some experiments

finaly I have could find the cheapest solution:

Take a cheap ballpoint with a flexibel plastic ink refills

inside. They have a little hole on the end side where you can

stick in this brown ink refills from Monteverde.
The brown color of this Monteverde refills
is a excellent classic sepia brown like the
sepia ink.
Below two examples of ballpoint drawings
from Henry Moore.
