So I made this yesterday with a birdcaller, pipe fitting, and doorknob. I'll be honest It's my second pipe and I'm damn proud. I have no bud but I tested with some K2 and my lungs were begging for mercy. Btw first post!
I took all that into consideration, I'm not sure what the exact material of the bowl is but It's not plastic, I held my lighter up to it and nothing. So it's all good
