Well...... As chalk, it is good and works prefect. The only reason I give 4 stars is it is too easy to break into pieces. It comes with cube shape. But when I opened the paper bag, it totally broke into many many small pieces. I know, it finally goes into powder, however, the big piece is easy to carry, that is why I purchase a cube shape. But.............hmmmmmm........ Also, i purchased other brands gym chalk cube, they are much tougher which made me use it longer.
