This is a spiral cymbal made by modifying a PAISTE PST5 series 18-inch Rock Crash cymbal. When hung, it extends to about 100 centimeters. It is made by modifying a used cymbal, so there may be rust, dullness, and dirt. The cut surfaces and edges have been deburred and polished to prevent injury, but please understand that this is amateur work. If you have any questions or concerns, please comment. Thank you for looking.
