The Kaweco palm green 50ml fountain pen ink refill provides a fluid and natural writing experience through a generous glass inkwell. The traditionally designed 50ml bottle contains quick-drying, highly soluble water-based ink that prevents clogging in fountain pens with integrated converters or pistons. The fresh and intense palm green shade brings vibrancy to the page without tiring the eyes, making it perfect for elegant correspondence, bullet journals, and botanical notes with an organic and refined character.
