A ballpoint pen refill lasts longer than an ink cartridge because ballpoint pens use a thicker, oil-based ink that requires less frequent replacement compared to the liquid ink used in cartridges. The ballpoint pen's design also allows for more efficient ink usage as it only dispenses ink when the ballpoint is pressed onto the paper. In contrast, ink cartridges continuously release liquid ink, leading to quicker depletion. **
