Best on the market , tasty and crunchy
This chalk is a bit pricey but it is the best on the market, tasty , good crunch, no weird smell and no gritty bits. No artificial or soap after taste either like with many others... I have ordered multiple times as I lack calcium and every time the chalk is excellent. Recommend.
