6-Arm Downstem Diffuser

Mathematix Glass equip the piece with a highly effective 6-arm downstem diffuser. Each arm of the diffuser contains two slits to help produce optimal smoke diffusion.  As the smoke particles separate through the slits, the smoke diffuses into a larger number of small bubbles, which in turn lowers the temperature of the smoke. The end result of this diffusion is a significantly cool and smooth hit for the user.

Ice Notches

Mathematix Glass include the forever in demand 3-pinch ice notch system at the neck of the glass piece. Dropping a number of ice cubes down the tube, this forces the smoke to pass through the ice and delivers the user with refreshing, chilled hit.

Removable Bowl

As the male 14.5mm bowl slide is removable, the user can easily insert their own vapor dome and nail. Converting this well-crafted glass bong into a dab rig for which you can use your chosen concentrates. Looking to turn this piece into a dab rig?
