I assume this is a 500ml bottle of ink, but there is no measurement listed on the label.
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.
Note: The bottle of 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...
