Pilot FriXion Ball Blue Erasable 0.7mm PK12

NEVER cross out again with FRIXION BALL, the ORIGINAL erasable pen from Pilot!
Pilot's best-selling rollerball allows you to cleanly write, delete (FriXion It) and rewrite - all with the same pen. Simply rub out your mistakes with the eraser stud and watch the ink disappear as if by magic! The unique gel ink responds to the heat generated by the rubbing out, and lets you write over your mistake immediately with the same pen.
Available in a variety of shades there's a FRIXION for everyone!
Save yourself money and be kind to the environment by refilling your FRIXION pen instead of buying a new one - it's never been easier to be green!
0.7mm tip gives a 0.35mm medium line.
