This is the perfect bowl for the Session Goods bong. The bowl that comes with is has a huge hole which is kinda useless. I looked all over for a 10mm bowl until I found this. It works fine with the Smojo screen (https://www.420science.com/products/smojo-permanent-smoking-screen?), but with it, your piece will stay amazingly clean. :) Highly recommend! Thinking about getting more, but the shipping to Canada was a little too much...
Great for snaps
