LILINY 18MM by 14MM STEM Standard Diffuser Clear 4 INCH 2-Pieces

At first, you may have a bit skeptical of this slider, with its bulbous head and yet seemingly shallow bowl.
It actually holds more than you think, and it hits VERY WELL!!! The smoke builds up INSIDE the head of the bowl and stem, not to mention the pipe itself. And it was smooth, not taking into account that you'll generally pull in more smoke than you realise! Great price, great product all around.
