This is a spiral cymbal made by modifying a PAISTE PST7 series 18-inch China cymbal. Here's a video of the cymbal being played: https://x.com/bsqdufni4s2385/status/2007247401527193830?s=61&t=igXDwr89IwOmhJgPIzbZ1A Copy and paste the address into your browser, or search for the X (Twitter) ID: bsqdufni4s2385 Please note that inquiries and transactions are only handled through Mercari. When hung, it extends to about 100 cm. This is a modified cymbal based on a 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.
