Pro-Tip: To ensure the brightest and most accurate lines, always shake the chalk reel before each use to fully coat the string. When snapping lines on damp surfaces, use a "double snap"—snap the line once into the air to shed excess chalk, then snap it again against the surface for a crisp, bleed-free mark.
