It's a little bigger then I expected, but a perfect fit for my 18mm banger. Over all; very well made, thick glass, and looks great.

Work's perfectly on most flat top and angled bangers, pretty sturdy as well. I broke the first one after a couple years and just bought another, they're perfect for $10!

It was a grate product over all amazing the only problem was it was way to big for my attachment maybe they can specify the size of each carb cap to better choose the proper one. Everyone has a diffrent attachment for there dab rig so 420science you were 1 star away to beeing the best

This is a great standard carb cap. A word of warning however, after the first time I use this, I fell asleep and the carb cap slept with my wife.
