Fully disposable fountain pen provides the smooth flow and feel of a fountain pen with smooth flowing, fast drying ink, yet offers the convenience and inexpensive throwaway price of a ballpoint. No more messy refills to deal with. Enjoy the luxury of silky smooth expressive lines with the medium size 0.7mm iridium nib for improved strength and resistance. And don't waste a drop of this pen's larger supply of ink. Just look into its viewing window to see how much you have left.
