Hey guys, quick question! I recently purchased a bottle of Mont Blanc Toffee Brown ink, and the color is amazing. However...the ink starts out nice and brown, and dries an almost greenish, moldy color. I've look around and I haven't seen anyone with the same problems as I have had. There is also some green residue inside the cap and around the glass rim, which has me thinking, again, about mold. Has anyone else experienced the same thing? Thanks!!
