Spider glass 2nd quality 2 hole with huge opal

Fumed spider glass 2 hole puffco top that is marked as a 2nd quality never was able to figure out why. There is some staining on the glass that won't come out with iso but if you give it a good clean I would imagine it would come out. Also if you need more pics just shoot me a message. I'm gonna actually try to clean it using cleaner instead of iso and will unmark it as sold once it's finished 🙏🏼
