Affordable piston-filling fountains
TWSBI fountain pens (TaShin Precision, Taiwan) are known for their large ink capacity, piston-filling mechanisms and transparent designs. They feature German-made nibs, which perform well straight out of the box. The TWSBI Diamond 580 serves as the everyday writer, equipped with a screw-off nib unit for easy nib size changes or compatiblility with the TWSBI Diamond 50 Inkwell.
