So my buddy and I love using screen bowls specifically 5 hole. when I saw how many holes i knew i had to try. I have a basic 12 inch 18mm beaker and its airflow is already amazing, putting this bad boy in there makes it a whole new level almost too much, Im buying an ash catcher to see if it helps smaller bongs. Now my buddy has a 20 inch bong with 2 percs and a 28mm downstem. This bowl is worth every bit of money, I use to have trouble taking full bowl rips especially with roach weed and man i can clear the entire bowl no problem when it comes to these huge bongs.

Always on points!

god bless

I purchased an 18mm built in disc screen Bong slide bowl with handle.

it's thick glass, yup. very very well made - nothing to note other than the good rips.

Perfect bowl piece. Good air flow. Quality thick glass well built and designed.
