The Pilot FriXion Waai is a retractable gel pen with Pilot's thermo-sensitive FriXion ink, which erases by friction from the built-in tip rather than by abrasion. It writes a 0.5 mm line and comes in softly toned pastel barrels, made in Japan. It suits students, planners, note-takers and anyone who drafts by hand and needs to undo mistakes without crossing out. Against ordinary erasable pens it erases more cleanly and rewrites repeatedly, but the ink is heat-sensitive, so it fades in hot cars and cannot be used on legal or exam documents where permanent ink is required.
