TWSBI

Watch your ink come alive

TWSBI fountain pens are known for modern piston-filling mechanisms, ink capacity and transparent designs. Fitted with German made nibs, they perform well straight out of the box. The Diamond 580 is the everyday writer, with a screw-off nib unit for easy nib changes and compatibility with the Diamond Inkwell. The Eco offers a simplified design with a friction fit nib and feed, but also options with plated trimmings. 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 shimmer inks and our artist sketch kits. For further help with pen selection, see the TWSBI Top 7 pens annotated by our staff. Visit our Blog for tips on pen cleaning and piston servicing.
