PILOT FriXion 07 / 0.35 mm, blue - pack of 6

If your Frixion pen ran out of ink, you don't need to buy a new one right away, just use this refill in blue colour. Just like the original Frixion cartridge, its ink is can be erased when heated by friction to a temperature above 65 °C, which the "rubber" at the end of your pen is for. The tip diameter is 0.7mm and the trace left on the paper is 0.35mm wide.
