These pens vary in ink delivery systems and writing experiences. For example, ballpoint pens use thick oil-based ink and a rolling ball mechanism, making them convenient and less messy. Gel pens use water-based gel ink, offering vibrant colors and smooth lines. Fountain Pen differs significantly it has a nib and uses water-based liquid ink, either through cartridges, converters, or built-in reservoirs. Writing with a fountain pen offers a more fluid and elegant experience, and many users enjoy its customizable nature and vintage feel.
