Make mistakes disappear! The Pilot Frixion Biz 2 is a seriously clever pen that lets you write in two colors and erase cleanly. It's a 2-in-1 ballpoint with both black and red ink in a single, sleek gray barrel. Just twist the top to switch between colors – super convenient for editing, note-taking, grading, or planning. The magic is in the special thermo-sensitive ink. When you rub the eraser tip (located on the cap) over your writing, the friction generates a bit of heat, making the ink become invisible. No messy rubber shavings or torn paper! Important note: because the ink is heat-sensitive, avoid leaving pages in hot cars or near heaters, as the writing could fade. Conversely, putting 'erased' notes in the freezer might make the writing reappear. It's refillable too, so you can keep using the pen body for a long time. Model number is LFBT-3SUF-GY. Perfect for students, office workers, journalists, or anyone who likes to keep their notes neat and changeable. A fantastic tool for bullet journaling, to-do lists, or signing documents where you might need a quick correction. Write, switch, erase, repeat!
