This appears to be a 500 ml. bottle of ink but there is no listing of size — Check the photos for current ink level.
I have had several inquiries... YES, this vintage ink works perfectly — ink doesn't spoil or go bad. I have been using vintage ink for many years now for both my fountain pens and with my dip pen nibs, and it has worked perfectly everytime. If there is some sediment in the bottle it is due to evaporation, and it will settle at the bottom of the bottle, so pull your ink from the top.
Note: The bottle of current day Pelikan ink in the photos is there for size comparison. The ink will well sealed, wrapped and shipped in a medium flat rate box through USPS.
I am currently selling off my collection of inks. So stay tuned...
