Four-color ballpoint pen with light blue body

The Frixion Ball 4 series features new bright colors. It contains four different colors of erasable gel ink in a single pen. The ink is thermosensitive and becomes invisible when rubbed with the built-in rubber on the top of the pen. Unlike traditional erasers, it does not leave residue, allowing you to write repeatedly in the same spot. However, it is not suitable for documents that require permanence, such as certificates or addresses.
