In contrast to chalks made of gypsum (calcium sulphate), which were used earlier, Jolly<\/span> only uses calcium carbonate. Real chalk from Jolly<\/span> is dust-free and easy to wipe off! From the school board to the bistro board, the classic school board chalk is a favourite writing instrument. There is even a practical chalk holder for the round chalk! The 4-edged version of the school chalk is available wrapped or pure as well as in colour!<\/p>","link":"https:\/\/jolly.at\/en\/produkt-kategorie\/accessories-en\/chalks\/","name":"Chalks","slug":"chalks","taxonomy":"product_cat","parent":127,"meta":[],"menu_order":14,"acf":[],"_links":{"self":[{"href":"https:\/\/jolly.at\/en\/wp-json\/wp\/v2\/product_cat\/128","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jolly.at\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/jolly.at\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/jolly.at\/en\/wp-json\/wp\/v2\/product_cat\/127"}],"wp:post_type":[{"href":"https:\/\/jolly.at\/en\/wp-json\/wp\/v2\/product?product_cat=128"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
