PRANG HYGIEIA CHALK
Hygieia White Dustless Chalk is made of 95% pure calcium carbonate.
This high percentage of pure levigated or refined chalk means it is virtually free of grit, greasy binders, or other ingredients harmful to board surfaces. This high quality produces a clean,
white mark, easily legible anywhere in the classroom. It erases easily (the heavier particles settle in the chalk tray and significantly cut down on dust). Hygieia outlasts ordinary chalk, and actually preserves chalkboard surfaces by keeping the “tooth” of the board in perfect writing condition.
One gross of 3-1/4" x 3/8" sticks are packaged in 12 stick sleeves,
tuck top boxes or in 36 stick Thrifti-Pac boxes and shipped in a sturdy container.
