Pentel Frixion series

Pilot FriXion pens are truly unique. Highly effective erasable pens with incredible heat-sensitive ink. Heat generated by the friction of the eraser causes the ink to become clear. No mess, no dust, no paper damage and completely 'erased' lines. You can then re-write using the same pen. A truly revolutionary pen range. Ideal for school and perfect easy-correct pens for dyslexics!
