What is another word for ballpen?
Pronunciation: [bˈɔːlpɛn] (IPA) 
Ballpen, also known as ballpoint pen, is an incredibly useful tool essential for everyday writing tasks. However, there are several synonyms that are used to refer to this ubiquitous writing instrument such as biro, ballpoint, stick pen, rollerball pen, gel pen, and fountain pen. These synonyms vary based on the ink composition, pen design, and writing style. A biro, for instance, is a type of ballpoint pen characterized by its low viscosity ink and robust design. Gel pen, on the other hand, uses pigmented ink that dries quickly, while fountain pens use liquid ink that is delivered through a nib. Regardless of the synonym, the pen remains a crucial tool for any writer and student.
