Eco-friendly chalk
A marketing phrase. The useful questions are ingredients, packaging, and how much you waste.
There is no agreed eco label that this site can point to for liquid chalk. A smaller bottle you finish is less waste than a large bottle that dries out. Loose chalk spilled on the floor is wasted mineral. Liquid used by the pea-sized squeeze wastes less of it.
"Organic" and "eco" on a sports bottle are claims. Ask what they refer to: the magnesium source, the alcohol, the plastic, or none of those. If the page does not say, the claim is empty.
