Prepare to be amazed... The Pilot Frixion looks and works exactly like an ordinary pen but the ink can be rubbed out using the friction eraser tool on the end. The medium 0.7mm nib delivers the intense black ink beautifully and precisely. And if you make a mistake no more crossing out or messy scribbles. Impressed? So are we. Pack measures approx. 210 x 70 x 20 mm Pack includes 2 pens Ink type; erasable rollerball ink Ink colour; black Pens are refillable
