Frequently Asked Questions

How do I fill the TWSBI ECO with bottled ink?

Submerge the nib and feed completely into your ink bottle. Turn the end piston knob counterclockwise to drive the plunger forward, then slowly twist it clockwise to draw ink into the barrel reservoir. Blot the nib and grip clean with a soft tissue.

Can I use standard ink cartridges or converters with this pen?

No. The TWSBI ECO features a dedicated built-in piston mechanism designed exclusively for bottled ink, offering more than double the ink capacity of conventional standard cartridges.

How do I maintain and lubricate the piston?

When turning resistance on the rear knob increases over time, use the included wrench to unscrew the piston assembly, apply a tiny smear of the provided silicone grease to the piston seal, and thread the mechanism back into the barrel.
