Montblanc ink bottle 50ml Elixir Calligraphy yellow gold 119592

"To complete the Meisterstück Calligraphy Collection, two types of permanent ink inspired by china have been created, one of the oldest and most durable pigments. Permanent ink contains more solid elements than other inks, which over time form residues within the fountain pen. The water present in the ink, which makes it fluid, evaporates, leaving lumps and residues that accumulate in the thin grooves of the ink flow regulator and plunger system. That is why it is important to always clean the fountain pen with warm water after using permanent ink, to keep it in perfect condition. "
