The Dome Mini Beaker Bong is simple in function and easy to clean! It's made from clear borosilicate glass with a round-top chamber. This type of body style is ideal because it allows more room in the chamber for smoke accumulation and larger rips, even from a relatively small pipe like this one! The flat base is also extra stable on most surfaces compared to other round shapes. A fixed interior downstem provides a bit of quick water diffusion to smoke as you inhale. Each bong includes a 14mm male herb slide.
