This is a pen that uses a gel based ink.
The FriXion Ball Knock pen has a 0.5 mm tip, easy for creating detailed annotations and diagrams, while also being great for smooth everyday writing. Its slim design makes it handy to transport and even better to grip. The FriXion Ball features a fully retractable nib, activated by pushing down the clip at the top of the pen. However, the real advantage of the FriXion pen is its disappearing ink, for all the perfectionists among us. We all make mistakes but the FriXion ink allows you to erase them by using the eraser at the tip of the pen without damaging your documents. The FriXion Ball Knock comes in a variety of colours, this one being Green.
