Arizer Glass Connoisseur Bowl by VGoodiEZ

I did not buy these from here but I will when I need more. Yes, you may need a M-M adapter but I get great air flow from these and you can have a shallow bowl or a party bowl on one piece. It works just fine with my Old Head Terp Hammer and my WOHW SS V2 Hammer also. Discovered this when I was in a pinch for a glass bowl and have and Arizer Tower and hey, it works great and it's two bowls in one at a great price.
