FriXion Waai is PILOT’s slim, off-white take on the FriXion erasable gel pen. Writing is erased by rubbing with the tip on the end of the barrel the friction heat clears the ink with no eraser debris, so it works in a library, a caf, or a planner. The ink colours are muted rather than primary.

• Tip: 0.5 mm extra fine
• Retractable, refillable
• Erasable thermosensitive gel ink; erases completely at around 65C of friction heat
• Total length 142 mm, maximum diameter 10.5 mm
• Off-white body with a rounded grip
• Model BL-RT-FRW7

Because the ink is heat-sensitive, writing can fade if left somewhere hot (a car in summer, near a heater). Not recommended for documents that must be permanent.
