Fountain Pen with Clear Demonstrator Body, Rainbow Iridescent Trim, Piston Filling and Multiple Nib Sizes

TWSBI Fountain Pen

This fountain pen combines a clear demonstrator body with a piston ink-filling system, letting you view the ink color and remaining level while writing. Rainbow-colored iridescent trim and an iridescent-accented stainless steel nib add a distinctive finish for everyday writing, journaling or collecting.

The pen has a clear grip section, screw-cap and detachable parts, and it is presented in a modern clear display case. A wrench and silicone grease are included for long-term care and maintenance; take extra care if disassembling the nib and feed because the feed is very fragile.

Choose the nib size that matches your writing style: Extra-Fine, Fine, Medium, Broad or 1.1mm Stub.
