I teach costuming and this chalk is perfect for marking on fabric. It brushes off easily, much better than tailor's chalk.

This is the best chalk I've found. I like soft chalk because it writes dark so that students can see it. This is more important to me than how dusty it is. This chalk shows up very well on my blackboard. Most chalks do not.

This chalk is very vivid and provides a beautiful contrast on even dirty boards. It also writes with a very soft sound, not like the sounds of a rock or fingernails, as I had expected.

This chalkboard is a gift for my grandson. I am very pleased with the quality and the price is unbelievable.

This is a really "clean" chalk and a great value.

A lot of my therapy must be done on a chalkboard. For the past 2 years I have spent hours in a windowless,8x12 (or so)foot room with my students and the chalk dust is almost unbearable. I swore I had tried every "dustless" chalk in the city and then ran across this product in our local Office Depot. I only bought 2 boxes because I didn't want to have a lot of poor "dustless" chalk on hand. By the time I went back for more of this wonderful product, the store had quit selling it. Today I got smart and "went online" and low and behold - there it was, listed with your company. Hooray! It is soft enough for our therapy and produces less dust than any I have tried thus far!!!
