    The Ultimate Chalk!
  

*by E***C on Reviewed in the United States on January 3, 2012*

This chalk does exactly what it claims to do! This chalk combined with an Irwin Speed-Line Pro Chalk Reel leaves an excellent mark that doesn't come off. The line is crisp, waterproof, and scuff proof. I wish I would've purchased this chalk sooner.
