This is a Yanagisawa ligature, also known as a "Yany Ligature." The finish is GP (Gold Plated). I purchased it but have stored it without using it much. I believe there are no noticeable stains, but please understand that it is a used item before purchasing. ★If you have any questions, please feel free to ask in the comments section!
