This is a spiral cymbal made by modifying a 16-inch A Zildjian medium crash cymbal. When hung, it extends to about 105 centimeters. It produces a soft, warm, trashy sound. This item is a modified used cymbal, so there may be rust, dullness, and stains. The cut surfaces and edges have been deburred and smoothly polished to prevent injury, but please understand that this is amateur work. If you have any questions or concerns, please leave a comment. Thank you for looking.
