Skull ring. I can't read the engraving, but based on the texture, it's likely silver. I suspect it's from the 90s or earlier, when regulations weren't as strict. Purchased at a used clothing store over a decade ago. I don't have any further details, so please judge based on the images. I apologize that I don't know the size. (I am 175cm tall, 65kg, and usually wore it on my left index finger) For those who understand vintage items, please purchase with the understanding of no returns, no refunds, and no exchanges. To prevent swapping, please note that cancellations will not be accepted under any circumstances. *For the prevention of problems, only those who understand Japanese, please.*
