What sets the ballpoint pen apart from other writing tools like fountain pens is its innovative ball mechanism. Inside the tip, you'll find a small rotating ball creating a 'nib'. This tiny ball is responsible for dispensing the ink onto the paper as you write, allowing for effortless gliding and a clean, smudge-free finish. This design makes the ballpoint pen perfect for both left and right-handed individuals. If you value durability, the ballpoint pen is an excellent choice. Its sturdy construction ensures that it can withstand the rigors of daily use, and ink leakage is not a problem unlike some fountain pens.
