The FriXion erasable pen line from PILOT works perfectly on TerraSlate when you would like to write and erase, or write and wipe clean with a damp towel.  

Note that we do not mark up the price on the pens as we sell them at cost.

• Combines the convenience of a retractable with the incredible FriXion erasable gel ink
• Erase and rewrite repeatedly without damaging documents - Eraser is at the top of the pen; tip is retractable by pressing clip down
• Unique Thermo-Sensitive gel ink formula disappears with erasing friction
