Thank you for viewing. The top is a WILD600 and the bottom is a WILD900 combination. Weight: Top: Approximately 1050g Bottom: Approximately 1300g Unfortunately, both have cracks in the center hole. Currently, it doesn't seem to have a major impact on the sound. These are rare 15-inch cymbals. Both are sheet bronze cymbals, with an image similar to Paiste. I loved them and collected them, keeping them carefully. I am reluctantly selling them this time due to various circumstances. Feel free to comment!
