color changing - blue to neon yellow

Monteverde Color Changing Blue to Neon Yellow is a vibrant tropical blue ink that dramatically transforms into a bright neon yellow when applied with the special Color Changer solution, offering a magical, instantaneous color shift ideal for artistic effects. Known for its smooth flow thanks to the ITF formula and fountain pen safety, it behaves like a normal ink until activated, though it may feather on some papers. It suits creative users, artists, and fountain pen enthusiasts seeking novelty and whimsy rather than everyday reliability.
