TWSBI

Affordable piston-filling fountains

TWSBI fountain pens (TaShin Precision, Taiwan) are known for piston-filling mechanisms, ink capacity and transparent designs. The pens feature German-made nibs, which perform well straight out of the box. The Diamond 580 serves as the everyday writer, equipped with a screw-off nib unit for easy nib size changes and compatiblility with the Diamond Inkwell. The Eco offers a simplified design with a friction fit nib and feed. Lesser known models include vacuum fillers with an ink shut-off valve for travel and the Swipe offering the convenience of standard cartridges or a spring converter. Good value range of soluble fountain pen inks supplied in frosted glass bottles. TWSBI pens are high flow, making them the ideal choice for our artist sketch kits. For further help with pen selection, see the TWSBI Top 7 list annotated by our staff. Visit our Blog for tips on pen cleaning and piston servicing.
