This is a basic bell. It offers a solid tone at an affordable price. The bell's powerful, long-lasting sound creates a solemn atmosphere, warding off evil thoughts, praying for the presence of the heavenly deities, and calming the mind of those who worship. It is struck lightly at the beginning and end of sutras. Material: Brass. Country of Origin: Japan. Product Dimensions (cm): Height 4 x Width 7.5 x Depth 7.5. 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. Because it is made of brass, a patina may develop over time.
