Color: Gold 200 yen discount without the box. I'm not sure of the material, but I didn't get a rash even though I have allergies. For reference, I get a rash from silver 925. I also get a rash from some titanium products. Lately, I can only wear gold or surgical stainless steel accessories because of my allergies. Usage: I wore it a few times when I was younger and then stored it. I tried wearing it again, but it doesn't suit me at all, so I'm selling it.
