This is a basic bell. Crafted from a material called sand-bari, it produces a clear, mellow tone that continues uninterrupted. The bell's powerful, long-lasting sound creates a solemn atmosphere, and its powerful, sustained tone is said to ward off evil thoughts, pray for the presence of the heavenly deities, and calm the mind of those who worship. It is struck lightly at the beginning and end of sutras. Material: Sahari. Country of Origin: Japan. Product Dimensions (cm): Diameter 9.2 x Height 5.1, Weight: 240g. Actual dimensions may vary slightly. Care Instructions: Polishing with metal polish or chemicals may remove the surface coating, so please clean with a soft, dry cloth. Also, because it is made of Sahari (a type of copper alloy), a patina may develop over time.
