Roller ball pens use water-based ink that flows really smoothly and makes dark, clear lines with little effort. This makes them great for neat writing, drawing, or important documents where you want your writing to look sharp and polished. Water-based ink also soaks into the paper better, so it doesn’t skip or blotch. Oil-based pens like ballpoints dry faster and work well for everyday writing and shiny surfaces, but water-based ink gives a smoother and richer writing feel.
