Review on KINGPiiN Crystal Brooch Accessories Silver Black by Matt Nichols

I need this to wear my winter coat, unisex jewelry. Quite heavy, made of silvery metal with a print on the back. A needle strong enough to penetrate a large amount of tissue. Stones in front look like black jet type. I think it would be too hard to put on a blouse or something. Also, there are burrs on the back that can snag thin fabrics.
