Quo Vadis blog, they posted asking about how everyone feels about 1670 being continued into production until 2012. This of course raises questions, as it was an ink commemorating the 340th anniversary of J. Herbin (hence the name, 1670).
But now it's been 341 years, so should the ink be discontinued? Or should the bottle be changed but the ink still offered?
If there's one thing I know about Quo Vadis blog and Exaclair (the US importer of Quo Vadis, J. Herbin, Rhodia, Clairefontaine...) it's that they really listen to feedback from their fans and customers. If you have an opinion about this ink, definitely jump over there and post how you feel about it on their blog.
Go post! They will listen.
