Chalk doesn't get much better than this,
A little box of white chalk sticks. Each stick is wrapped in a paper sleeve to keep your fingers clean, well as clean as can be expected when using chalk.
Made in Germany by the country's oldest chalk manufacturer Drei Sterne.
Each chalk stick is approx 1.3 x 1.3 x 9cm. Comes in a cardboard box with 12 white chalk sticks.
