Dritz Tailor's Chalk, 2 Piece Blue and White

I use the white chalk more than the blue chalk, so I know how easy it is to brush off the white marks afterward. I wish this chalk would come in a holder/case with a built in sharpener like my last one did but I purchased that one many years ago. I used the old case sharpener to put a thin edge back on the new chalk and it works out just fine. It is a hard chalk so it doesn't crumble as I am using it. I feel like it is a good value. The blue chalk has come in handy too, I just use the white one more.
