At stores everywhere, you can find chops made from t'ai-lai stone and "green jade" stone which come in all sorts of different shapes and colors. Prices are low, generally NT $ 50 (or about US $ 1.70) for the price of a chop. These two types of stone are the most popular materials used to make library chops.
