Crooked lines, half-finished diagrams, and a whiteboard that looks like a toddler drew on it — you've been there. The Helix 60cm magnetic ruler sticks to your board exactly where you need it, so straight lines stay straight while both hands are free to write. The detachable handle eraser means you can correct mistakes without hunting for a separate eraser across the room. Grab it, stick it, draw a line that actually looks professional
