{"product_id":"prang-hygieia-dustless-board-chalk","title":"Hygieia Dustless Board Chalk","description":"\u003cp\u003eCalcium carbonate composition means this chalk delivers clean, opaque lines without the grit that scratches board surfaces. Prang formulates Hygieia chalk to 95 percent purity, eliminating the abrasive particles that cause streaking and pitting on well-used chalkboards. The dustless formula keeps airborne particles minimal, crucial for classroom environments and anyone sensitive to chalk dust.\u003c\/p\u003e\n\u003cp\u003eRound sticks measuring 3¼ × ⅜ inches fit standard chalk holders, maintaining comfortable grip whether you're writing equations across a full board or sketching quick diagrams. Each stick applies smoothly and erases completely, leaving boards clean rather than ghosted with residual marks. AP certification confirms nontoxic composition, meeting safety standards for educational settings.\u003c\/p\u003e\n\u003cp\u003eThis assorted box includes twelve sticks: two each of green, yellow, blue, pink, orange, and purple. Color-coding helps organize complex information, use different hues for variables, steps in a process, or distinct categories. The variety works equally well for classroom instruction, studio demonstrations, or menu boards where visual hierarchy matters.\u003c\/p\u003e","brand":"Prang","offers":[{"title":"assorted \/ set of 12","offer_id":47978400514277,"sku":"12406","price":1.1,"currency_code":"USD","in_stock":true},{"title":"yellow \/ set of 12","offer_id":47978400547045,"sku":"28551","price":0.91,"currency_code":"USD","in_stock":true},{"title":"white \/ set of 12","offer_id":47978400579813,"sku":"55008","price":0.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s12406.jpg?v=1770300984","url":"https:\/\/www.texasart.mom\/products\/prang-hygieia-dustless-board-chalk","provider":"Texas Art Supply","version":"1.0","type":"link"}
