KesonPM103BLUE ProChalk Permanent Chalk, Blue, 3-Pounds

Muy barato, buena calidad.

Great chalk. Long lasting

Never really been a fan of blue, but this is bright, bright blue. Paired with a braided line it's very crisp. Currently pouching a Lufkin 50' which I liked so much it sent the tajima's to the backup box. Number 4 permanence....not really so much on cdx in the wet. Perhaps it's different on OSB, but I'll never know because we don't use it. I'll get around to loading the Lufkin mini with some tajima line and see how that rolls, but so far I like it quite a bit

I use black to build to, red for corrections, blue for special. Holds up well to the job site and rain.

It is not really permanent on concrete like they lead you to believe, but it is very dark and if you touch it up every now and then it is very good for blue chalk

This is my husband’s favorite chalk. He uses it for work and finds it helpful to get the large quantity here so he doesn’t have to run to the store as often.

Bright. Im a commercial carpenter and it works better that anything I have use

Works

Very good product, right up there with the Irwin brand, used it to chalk concrete floors for layout and it rained and still visible
