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 just look into its viewing window to see how much of this pen's larger supply of ink you have left.
