I purchased two types, including the rosewood version. I preferred the rosewood ones, so these brass ones have been kept unopened. Although the packaging has some stains as shown in the image, they are unopened and unused. Since I don't plan to use them in the future, I hope someone who needs them will consider purchasing them. They will be shipped via Yu-packet Mini.
