The FriXion Colors is an innovative, erasable premium fiber pen filled with thermosensitive FriXion ink. It's perfect for when you've been a bit too enthusiastic while coloring, sketching, or doodling and have put too much ink on the paper. Simply rub the plastic tip on the cap over the paper, and the ink from the FriXion Colors disappears (at around 60 °C of friction heat). Thanks to the reverse effect, you can also create magical cards for your best friends, as your message will reappear like magic after a short time in the freezer (at around -10 °C)! Its stable tip with a medium line thickness provides excellent pressure control while coloring and detailing sketches—without fraying.
