Gray-metallic kostovite in bornite on matrix

==================================================

For all American bidders:

At the moment, it looks like there will be no 15% duty on collectibles. That's good news.

Unfortunately, shipping costs aren't back to where they used to be.

I have to charge all American customers €38 in shipping.

I also offer to combine multiple auction days into one package.
