I can't believe how short a time it has taken for me to replenish my ink supply. Mainly, due to the smaller size of Iroshizuku now being available. Now, have a nice growing supply of inks, several empty Goulet Pen Company vials. Question, where do you keep your inks? Nib tuning supplies? Empty Goulet Pen Company vials? So far, I have tried a plastic carriers, used for hobbiest; blue top, flaps on each side, carry handle on top. A smaller square one, clear top, rectangle flap which secures down on each end and carry handle. I don't cary my supply or inks outside, so mainly use them at home, where do you keep your inks? Where are your inks sitting right now, or when you decide to load your pens? If you have way more than one, less than a stationary store, how do you manage them in terms of space, until are ready to use?
