【Ultra Rare】Gyuukaku Frozen Chicken Blood Stone - Antique Seal Material

I've seen many chicken blood stones before, but it's rare to find one of this high quality.
Honestly, I don't want to let it go, but I'm releasing it from my collection.

The ox horn freeze alone is very valuable, but this is a chicken blood stone of that quality.
