TrueSet Marking Chalk Powder — 5 lb Refill (High-Vis Blue)

Ultra-fine marking chalk that lays down bold, sharp lines for grading limits, utility runs, and layout grids across an open parcel. Refills any standard chalk box so crews never run dry mid-layout.

• 5 lb resealable tub of finely milled high-visibility blue powder

• Bonds to dirt, gravel, and concrete for clean, readable lines

• Temporary formula fades naturally without staining finished surfaces

• Fills any standard chalk-line box or dispenser
  Bold marks, zero guesswork — the whole crew reads the same line.
