Pilot Penna Sfera Frixionball 0.7mm Blu

Pilot's Frixion erasable rollerball is a step ahead of the competition thanks to clever ink which turns transparent when subjected to friction. No eraser dust, and the line disappears very cleanly leaving only a faint impression of the erased line. The ideal way to erase is using the built-in eraser, though most hard plastic works OK. In fact if you're working on newsprint (eg. crosswords and Sudoku), the cap-end works better than the eraser as the eraser will smear the newspaper ink. 0.7mm tip. Refillable with Pilot BLSFR7 refills.
