So three new inks were added to Chesterfield's Antique line-- Antique Raven, Antique Mariner, and Antique Walnut. (left to right: Antique Walnut, Antique Raven, Antique Mariner) What do you guys think? I'm not a blue-ink person, but that Mariner looks pretty appealing. Judging by the swabs provided online, how do you think Raven and Walnut compare to maybe some of the greys from the Iroshizuku inks or other ink brands?
