Using this chalk holder can help keep your hands clean and protect the chalk from breaking. It also features a lateral window, allowing you to see how much chalk is left.

To use it, insert the chalk from the top. Then, unscrew the bottom part to let the chalk slide down. I prefer to place my finger at the bottom to prevent the chalk from sliding through completely.

The chalk size should be approximately 10 mm.
