Täytekynät

Täytekynät, or fountain pens in English, are writing instruments that use a metal nib to deliver ink to paper. Unlike ballpoint pens, which rely on a rolling ball to dispense ink, fountain pens feature a reservoir that holds liquid ink, which is then drawn to the nib through capillary action. This design allows for a smoother writing experience and a wider range of ink colors and properties.

The modern fountain pen evolved from earlier quill pens and dip pens, with the invention of the internal ink reservoir in the 19th century marking a significant advancement. Early designs often suffered from leakage and inconsistent ink flow, but continuous innovation led to more reliable and user-friendly pens. Today, fountain pens are appreciated by many for their writing comfort, aesthetic appeal, and the tactile pleasure they offer.

Fountain pens typically consist of a barrel, a section that holds the nib, the nib itself, and an ink feeding system. Ink can be supplied to the reservoir through various methods, including cartridges, converters that allow the use of bottled ink, or built-in filling mechanisms like piston or vacuum fillers. The choice of nib material, size, and flexibility significantly influences the writing characteristics of the pen, ranging from fine, precise lines to broad, expressive strokes.
