The Ballpoint Pen vs. The Rollerball: What’s the Difference?
One of the most frequently asked questions in our store is the difference between a ballpoint pen and a rollerball. This is a question we encounter often, so we’d like to take a closer look at it here. Although they may seem to have a lot in common at first glance, there are subtle differences that can make a world of difference in your writing experience. Let’s dive into the history and characteristics of these popular writing instruments.

This innovation solved the problems of leaking fountain pens and smudging ink and quickly became an essential tool for pilots during World War II due to its reliability under various conditions.
Today, the ballpoint pen is known for its versatility and durability. The thick, oil-based ink dries quickly, minimizing the chance of smudging, and the pen can write on almost any surface. It’s the pen you can rely on, whether you’re taking notes during a meeting or jotting something down quickly on the go.

This mechanism ensures that the
