These Tingsha are master quality and very difficult to source. Their sound is absolutely incredible. Many people do not appreciate the power of Tingsha because they have not experienced anything other than the tourist quality bells that are sold throughout Asia, usually with spiritual symbols on them. While such Tingsha are visually quite beautiful, they are not designed for professional use. These are. We can only source a small number of these at a time from Nepal so our stock is limited. If you order and we are out of stock, we will email you with a time frame for delivery of our next shipment. Each pair includes a case (colors vary).
