Beautiful shading. Tried it in a Lamy Safar no problems and shading shows beautiful, even on a Stalogy Paper (no TRP). No Clogging or other problems. Works even with a Pilot Kakuno , but without showing this much shading, a little lighter but still what I would consider as a beautiful "Blurple" For all who know Sailor Manyo Nekoyanagi: similar but Milky Ocean is a little bit darker.
