Frixion Erasable Pen .7mm Turquoise Blue

These Pilot Frixion Erase Pens have a .5mm line and write with a smooth flowing gel ink, which is erased with the heat from the frixion eraser.  These pens are great for school and office work, and are also quite handy for art purposes; you can layout your art and use a hair drier to erase your lines after inking in the lines you want.
