Got what I paid for
Fun little gift or part of a personal collection. I strongly recommend handling with gloves as pure copper stains very easily (from experience, unfortunately.) donโt have tools to verify purity unfortunately

Very nice, just as advertised, but SHARP
Unless you are never planning to handle it like a desktop fidget thing, you will want to round off the edges a little...they are very sharp
