The Frixion pen is a unique writing instrument that uses a special gel ink, which can be erased with friction. This innovative design allows users to write smoothly and then easily remove their writing by rubbing the tip of the pen against the paper. The ink becomes transparent when heated, making it ideal for corrections without leaving any residue. Available in various colors and tip sizes, the Frixion pen is popular among students, professionals, and artists. It is also refillable, making it an eco-friendly choice. The pen's versatility and ease of use have contributed to its widespread appeal in everyday writing tasks.
