Ultra-pure (~99% magnesium carbonate), high-performance chunky chalk is made from the mineral contents of seawater. No destructive mining here! This chalk is a byproduct of the salt industry and is produced using natural processes such as solar evaporation. This, combined with plant-based 🌱 packaging (which is also fully recyclable! ♻️) leads to a lower energy and environmental footprint vs. other chalks.
