PILOT Frixion 07 / 0.35 mm, 4 colours - pack of 6

If your Frixion eraser pen has run out, you don't need to buy a new one right away, just this original replacement refill. Like the original Frixion refill, its ink is "erasable" - it erases when heated by friction above 65°C, which is what the "eraser" at the end of your pen is for. The tip diameter is 0.7 mm and the trace it leaves on the paper is 0.35 mm wide. This handy pack contains 6 spare refills in four colours - blue, black, red and green.
