In a pen, the ink is held in a reservoir, which can be a cartridge, converter, or ink chamber, depending on the type of pen. Ballpoint and rollerball pens use refillable or disposable ink cartridges, while fountain pens have converters or built-in reservoirs. The nib or tip controls the ink flow, ensuring smooth writing. Using high-quality Pen Accessories like ink refills, converters, and cleaning kits can enhance a pen's performance and longevity. Parker Pen Pakistan offers a wide range of premium pens and accessories, ensuring an exceptional writing experience. Choosing the right accessories helps maintain ink flow and keeps your pen in top condition.
