I've been informed that Exaclair (the sole US J. Herbin importer) has possession of replacement wax dipped caps for the 1670 ink bottles. The first batch of the inks had a brittle wax that would crack off to reveal the metal cap underneath. Not so sexy. If you're interested in getting a new replacement cap for your bottle of 1670 from the original batch, just email me to let me know and I'll get you a new cap. I am going to have a bunch on hand, but if I get more requests for them I'll work with Exaclair about getting more. I don't know at this point if there's any cost involved.
