Do you carry extra ink? If so, how do you do so?
At any given time, I have 1-3 pens on me. I spend a good deal of time at work so I naturally keep the ink at my work desk. Due to the inner shape of the baby 2l bottle tubes, only one vial of the Goulet ink sample vial fits inside. I thought about boring the inside out to allow room for a 2nd vial to fit.
Thoughts?
