This is my first question on this forum, so I don't know if I'm in the right place.
Anyway, I'm a college student that writes exclusively with fountain pens. I prefer piston fillers (my current daily driver is a Reform 1745). Being a student, my budget is very modest, meaning that if I need a portable inkwell, I cannot afford the Visconti Portable Inkwell. Does anybody know of any alternatives, either modern or antique, that could allow me to carry some ink in case I run out?
Preferably, it would be reasonably-priced, sturdy enough to keep in a bag, and have a pretty small form factor. It doesn't need to hold a whole lot of ink, just enough to keep me going if I still need to write a page or two more after my ink runs out. Also, I would actually prefer if it wasn't something really fancy looking. I don't want to draw attention to myself by pulling it out in the middle of class.
